If you’re searching for information on 10mm shoulder bolts, you likely need to know what they are, how to choose the right one, or how to use them effectively. Проще говоря, а10mm shoulder bolt is a specialized fastener with a cylindrical “shoulder” (a smooth, unthreaded section) that’s 10mm in diameter, followed by a threaded section. This design lets it act as both a pivot point and a fastener, making it ideal for applications like hinges, pulleys, and machinery where precise alignment and smooth movement are key. В этом руководстве, мы расскажем все, что вам нужно знать — от основных характеристик до расширенного устранения неполадок — чтобы помочь вам максимально эффективно использовать этот важный компонент..
Что такое болт с буртиком 10 мм??
Начать, давайте разберем ключевые компоненты и назначение болта с буртиком 10 мм.. Unlike standard bolts, which are fully threaded, shoulder bolts have three main parts: аголова (for tool engagement, like hex or socket), аплечо (the smooth, 10mm-diameter unthreaded part), иthreaded shank (the part that screws into a mating component).
The shoulder is the star here—it’s precision-machined to tight tolerances (often ±0.01mm for diameter) to ensure a snug fit in a drilled hole. This allows parts to rotate or slide around the shoulder without wobbling, which is why 10mm shoulder bolts are common in applications like small motors, 3D Принтеры, и медицинские устройства. Например, in a desktop 3D printer’s extruder, a 10mm shoulder bolt acts as the pivot for the idler pulley, keeping the filament feed smooth and consistent.
Основные характеристики, которые необходимо знать
Not all 10mm shoulder bolts are the same. Here are the critical specs you need to check before buying:
- Shoulder Length: This is the length of the smooth 10mm section. Common lengths range from 5mm to 50mm, and it needs to match the thickness of the parts you’re joining. If the shoulder is too short, parts won’t align; too long, and it will stick out unnecessarily.
- Thread Size: The threaded section (usually metric, like M5 or M6) must match the nut or tapped hole. Например, a 10mm shoulder bolt with an M6 thread is often used in light-duty machinery, while an M8 thread is better for heavier loads.
- Материал: Common materials include нержавеющая сталь (для коррозионной стойкости, ideal for outdoor or wet environments), углеродистая сталь (stronger but prone to rust, good for indoor dry applications), и титан (легкий и сильный, used in aerospace or medical tools). Настоящий пример: a marine pump manufacturer might use stainless steel 10mm shoulder bolts to prevent rust in saltwater conditions.
- Head Type: Шестигранные головки легко использовать с гаечными ключами., в то время как торцевые головки (как шестигранные ключи) лучше подходят для ограниченного пространства. В компактной электрической распределительной коробке, Болт с буртиком диаметром 10 мм с головкой под торцевой ключ часто является лучшим выбором..
Когда использовать болт с буртиком 10 мм (против. Другие крепежи)
Вам может быть интересно: почему бы не использовать вместо него обычный болт на 10 мм или шпильку? Ответ кроется в уникальных преимуществах конструкции плечевого болта.. Давайте сравним его с распространенными альтернативами, чтобы помочь вам решить, когда болт с буртиком 10 мм подойдет лучше всего..
| Тип крепления | Ключевое преимущество | Ключевой недостаток | Лучше всего для |
|---|---|---|---|
| 10мм Болт с буртиком | Точное выравнивание + застежка в одном | Более высокая стоимость по сравнению со стандартными болтами. | Повороты, pulleys, parts needing smooth movement |
| Standard 10mm Bolt | Бюджетный, widely available | No smooth shoulder—poor for alignment | Joining static parts (НАПРИМЕР., attaching a bracket to a frame) |
| 10mm Dowel Pin | Excellent alignment | Needs a separate fastener to hold parts | Permanent alignment (НАПРИМЕР., in a gearbox) |
| 10mm Eye Bolt | Can attach cables/ropes | No shoulder—no alignment for moving parts | Lifting or hanging light loads |
A practical case study: A furniture maker was using standard bolts to attach chair armrests, but the armrests wobbled because the threads didn’t allow smooth movement. By switching to 10mm shoulder bolts, they eliminated the wobble— the smooth shoulder let the armrests pivot slightly (для комфорта) while staying securely fastened. This small change reduced customer complaints by 40%, according to their internal data.
Another scenario: If you’re building a small conveyor system, the rollers need to spin freely but stay aligned. A 10mm shoulder bolt is perfect here— the shoulder holds the roller in place, and the threaded shank screws into the conveyor frame. A standard bolt would cause the roller to bind because of the threaded section, while a dowel pin would require an extra bolt to keep it from falling out.
Как правильно выбрать болт с буртиком 10 мм (Шаг за шагом)
Choosing the wrong 10mm shoulder bolt can lead to parts failing, machinery breaking, or safety risks. Follow this step-by-step process to make sure you pick the perfect one for your project.
Шаг 1: Рассчитайте необходимую грузоподъемность
Первый, you need to know how much weight or force the shoulder bolt will handle. This is called theshear strength (the force that would break the bolt) ипредел прочности (the force that would stretch or pull the bolt apart). Most 10mm shoulder bolts have published strength ratings:
- Нержавеющая сталь (A2 grade): Typical shear strength = 300 МПА, tensile strength = 500 МПА
- Углеродистая сталь (8.8 оценка): Typical shear strength = 450 МПА, tensile strength = 800 МПА
- Титан (Оценка 5): Typical shear strength = 600 МПА, tensile strength = 900 МПА
To calculate: If your application involves a pulley that carries a 50kg load, the shear force on the 10mm shoulder bolt would be around 500N (since force = mass x gravity, 50kg x 10m/s² = 500N). A stainless steel 10mm shoulder bolt can handle far more than that (its shear strength translates to over 20,000N for a 10mm diameter), so it’s a safe choice. Если вы не уверены, always choose a bolt with a strength rating 2-3x higher than your calculated load to account for unexpected stress.
Шаг 2: Сопоставьте длину плеч с вашими деталями
The shoulder length must be equal to the total thickness of the parts you’re joining. Например, if you’re attaching two metal plates (one 8mm thick, one 6mm thick), the shoulder length should be 14mm (8+6). If the shoulder is too short (say 10mm), the plates will overlap on the threaded section, causing binding. If it’s too long (20мм), the extra shoulder will stick out and could catch on other parts. A pro tip: Measure the parts with a caliper (не правитель) for accuracy—even a 1mm difference can cause issues.
Шаг 3: Выберите правильный материал для окружающей среды
Think about where the bolt will be used:
- В помещении, сухой (НАПРИМЕР., office furniture): Carbon steel is cheap and works well.
- Outdoor or wet (НАПРИМЕР., Садовые инструменты): Нержавеющая сталь (A2 or A4) Чтобы предотвратить ржавчину. A4 stainless steel is more corrosion-resistant than A2, making it better for coastal areas.
- High temperature (НАПРИМЕР., small ovens): Heat-resistant alloys like Inconel, but these are more expensive. For most low-temperature applications (under 300°C), stainless steel is fine.
- Medical or food industry: Titanium or 316 нержавеющая сталь (A4), which are non-toxic and easy to clean.
Шаг 4: Выберите правильный размер резьбы и тип головки.
- Thread size: The threaded shank should fit the nut or tapped hole. Common thread sizes for 10mm shoulder bolts are M5, M6, and M8. Use a thread gauge to check the pitch (НАПРИМЕР., M6 x 1.0 means 1mm between threads) if you’re replacing an old bolt.
- Head type: Hex heads (external hex) are good for easy access with a wrench. Socket heads (internal hex) are better for tight spaces where a wrench won’t fit. Например, in a small drone’s motor mount, a socket head 10mm shoulder bolt is ideal because there’s little room to maneuver a wrench.
Советы по установке болтов с буртиком 10 мм (Избегайте общих ошибок)
Even the best 10mm shoulder bolt will fail if installed incorrectly. Вот как сделать это правильно, plus common mistakes to avoid.
Инструменты, которые вам понадобятся
- A drill (with a 10mm drill bit for the shoulder hole—use a high-speed steel (HSS) bit for metal, a wood bit for wood)
- A tap and die set (if you need to tap a hole for the threaded shank)
- A wrench or Allen key (matching the head type)
- A caliper (to measure the hole and shoulder length)
- Thread locker (необязательный, for preventing loosening in vibrating applications)
Пошаговая установка
- Drill the shoulder hole: The hole for the smooth shoulder must be exactly 10mm (or slightly larger, 10.01-10.03мм) to allow easy movement. Если дыра слишком мала (9.9мм), the shoulder won’t fit; Слишком большой (10.1мм), and the bolt will wobble. Для металла, use a cutting fluid to keep the drill bit cool and prevent overheating.
- Tap the threaded hole (При необходимости): If you’re screwing the bolt into a part (not using a nut), tap a hole for the threaded shank. Например, if the bolt has an M6 thread, use an M6 tap to create the threads. Make sure the tapped hole is deep enough—at least 1.5x the thread diameter (so 9mm deep for M6).
- Insert the bolt: Slide the bolt through the shoulder hole, then screw the threaded shank into the tapped hole or nut. Tighten it with a wrench or Allen key—don’t over-tighten! Over-tightening can strip the threads or bend the shoulder. A good rule: tighten until you feel resistance, then give it a 1/4 turn more.
- Add thread locker (необязательный): If the bolt will be in a vibrating environment (НАПРИМЕР., a power tool), нанесите небольшое количество фиксатора резьбы (как Локтайт 243) to the threaded shank before installing. This prevents the bolt from loosening over time.
Распространенные ошибки при установке, которых следует избегать
- Using the wrong drill bit size: A 9.5mm bit will make the hole too small, forcing you to hammer the bolt in and damaging the shoulder. A 10.5mm bit will make it too large, causing wobble. Always use a 10mm bit (check with a caliper).
- Over-tightening: This is the #1 mistake. A study by a fastener manufacturer found that 60% of shoulder bolt failures are due to over-tightening, which weakens the bolt and can break the threaded section. Use a torque wrench if you’re unsure—most 10mm stainless steel shoulder bolts with an M6 thread require 8-10 Nm of torque.
- Ignoring the shoulder length: If the shoulder is shorter than the part thickness, the threaded shank will be in the shoulder hole, causing binding. Always measure the part thickness before buying the bolt.
Техническое обслуживание и устранение неисправностей болтов с буртиком 10 мм.
To keep your 10mm shoulder bolts working well, regular maintenance is key. Вот как их обслуживать и устранять распространенные проблемы..
Регулярные задачи по техническому обслуживанию
- Inspect for rust or corrosion: Check outdoor or wet-use bolts every 3-6 месяцы. If you see rust, clean it with a wire brush and apply a rust inhibitor (like WD-40) or replace the bolt if the rust is severe.
- Check for loosening: In vibrating applications, check the bolt monthly. If it’s loose, tighten it or add thread locker.
- Lubricate moving parts: If the bolt is used as a pivot (НАПРИМЕР., in a hinge), apply a small amount of lubricant (like lithium grease) to the shoulder every 6 months to keep movement smooth.
Распространенные проблемы и способы их устранения
| Проблема | Причина | Решение |
|---|---|---|
| Bolt is loose and won’t stay tight | Vibrations or insufficient torque | Add thread locker or use a lock nut; retighten to the correct torque |
| Shoulder is stuck and won’t move | Ржавчина, грязь, or incorrect hole size | Clean the shoulder with a wire brush; apply lubricant; if the hole is too small, re-drill to 10mm |
| Threads are stripped | Over-tightening or wrong thread size | Replace the bolt; tap a larger thread (НАПРИМЕР., from M6 to M8) if the hole is damaged |
| Bolt breaks under load | Load exceeds shear/tensile strength; poor material | Replace with a higher-strength bolt (НАПРИМЕР., switch from stainless steel to carbon steel); reduce the load if possible |
A real-world troubleshooting example: A small manufacturing plant had a problem with 10mm shoulder bolts breaking in their conveyor system. After inspection, they found the bolts were carrying a load of 15,000N—far more than the stainless steel bolts’ 20,000N max (they didn’t account for shock loads). They switched to carbon steel 10mm shoulder bolts (с 450 MPa shear strength, translating to 35,000N max load), and the breakages stopped.
Взгляд Yigu Technology на болты с буртиком диаметром 10 мм
В Yigu Technology, we’ve worked with 10mm shoulder bolts in countless industrial and consumer applications, from 3D printers to medical devices. We believe the key to getting the most out of these fasteners is balancing precision and practicality. Many customers focus only on cost, choosing cheap carbon steel bolts for outdoor use—this leads to rust and frequent replacements, costing more in the long run. We always recommend matching the material to the environment first, even if it means a slightly higher upfront cost. Кроме того, we’ve seen how proper installation (using the right drill bit size and torque) can extend a bolt’s lifespan by 2-3x. For high-precision applications like robotics, we often suggest custom 10mm shoulder bolts with tighter tolerances (± 0,005 мм) to ensure smooth movement. Общий, 10mm shoulder bolts are a small but critical component—investing in the right one and installing it correctly saves time, деньги, and headaches.
Часто задаваемые вопросы о болтах с буртиком 10 мм
1. В чем разница между болтом с буртиком 10 мм и шпилькой 10 мм??
A 10mm shoulder bolt has a head and a smooth shoulder, while a 10mm stud is fully threaded (no head or shoulder). Studs are used to join two parts with nuts on both ends, while shoulder bolts are for pivot or alignment applications.
2. Можно ли использовать болт с буртиком 10 мм по дереву??
Да, but you’ll need to drill a 10mm hole for the shoulder and a smaller hole (matching the thread size) for the threaded shank. Use a wood tap to create threads, or use a nut on the other side. Avoid using carbon steel in wood that’s exposed to moisture—stainless steel is better.
3. Как измерить болт с буртиком 10 мм??
- Shoulder diameter: Measure the smooth section with a caliper (should be 10mm).
- Shoulder length: Measure from the base of the head to the start of the threads.
- Overall length: Measure from the top of the head to the end of the threaded shank.
4. Какую максимальную температуру выдерживает болт с буртиком из нержавеющей стали диаметром 10 мм??
Most A2 stainless steel 10mm shoulder bolts can handle temperatures up to 300°C (572° F.). Для более высоких температур (до 600 ° C.), use A4 stainless steel or heat-resistant alloys like Inconel.
5. Могу ли я повторно использовать болт с буртиком 10 мм??
It depends on the condition. If the shoulder is not bent, the threads are not stripped, and there’s no rust or damage, you can reuse it. Однако, if it was in a high-load or vibrating application, it’s safer to replace it—fatigue (hidden damage from repeated stress) can cause it to break unexpectedly.
