What Buyers Should Know Before Sourcing DIN 985 Nylon Lock Nuts
DIN 985 nylon lock nuts use a nylon insert to create prevailing torque on the male thread. They are useful for vibration resistance, but they are not the same as all-metal lock nuts. Temperature, chemical exposure, repeated reuse, tightening method, bolt grade, thread pitch, and coating thickness should be checked before selecting them for critical equipment or outdoor assemblies.
Nylon Insert Function
The nylon ring grips the bolt thread and helps resist loosening after tightening. For high-vibration equipment, buyers can compare DIN 985 nuts with other 防松紧固件 在完成组装之前。
Temperature and Reuse
Nylon insert lock nuts should be checked against working temperature and chemical exposure. For critical assemblies, new nuts are normally preferred because prevailing torque may reduce after repeated installation and removal.

材质及牌号说明
Carbon steel DIN 985 nylon lock nuts are commonly supplied for machinery, brackets, equipment frames, and distributor stock because they offer practical strength and cost control. Stainless steel 304 and 316 lock nuts are selected when corrosion resistance is more important. Class 8 nylon lock nuts are often matched with Grade 8.8 carbon steel hex bolts, while higher grades should be checked against the bolt, washer, and tightening method.
The nylon insert provides locking performance, but it also introduces temperature and chemical limits. For assemblies exposed to high heat, aggressive chemicals, or repeated removal, buyers may need all-metal lock nuts or another anti-loosening solution. For grade matching, see XZ Fastener’s guide to 螺母等级和螺栓扭矩匹配.
表面处理选择指南
Surface finish should be selected according to corrosion exposure, appearance requirement, mating bolt finish, and nylon insert limitations. DIN 985 lock nuts are commonly zinc plated or supplied in stainless steel plain finish. If coating requires high process temperature, the production route should protect the nylon insert.
| 完成 | 适合用途 | 采购考虑 |
|---|---|---|
| 镀锌 | 通用机械、设备组装、室内库存 | Common finish for carbon steel nylon lock nuts and compatible metric hex head bolts. |
| 黑色氧化 | 机械内部和黑色外观要求 | Usually requires oil or additional protection for corrosion resistance; can be matched with black oxide DIN 933 bolts. |
| 普通不锈钢 | Moist environments, food equipment, light marine exposure depending on grade | A2 and A4 stainless options should be selected according to corrosion conditions. |
| 达克罗或吉美特 | 户外设备和腐蚀敏感组件 | Confirm coating process and nylon insert compatibility before production. |
| Hot dip galvanized assembly | Outdoor bolt assemblies where heavy zinc protection is required | Standard nylon insert nuts are not usually hot dip galvanized after insert assembly; consider compatible matched parts or another lock nut type. Hot dip galvanized DIN 933 bolts can be supplied separately for related assemblies. |

制造和质量控制
DIN 985 nylon lock nuts are generally produced through nut forming, tapping, heat treatment when required, surface finishing, nylon insert assembly, inspection, and packing. The locking function depends on both the metal nut body and the nylon insert, so dimensional and prevailing torque checks are important for stable assembly performance.
- 对边宽度、螺母高度、倒角和螺纹深度检查
- 通过/不通过螺纹量规检查以确保公制螺纹兼容性
- Nylon insert position, appearance, color, and retention checks
- Prevailing torque testing when specified by buyer or project requirement
- Coating coverage, color, thickness, and thread build-up review
- 尺寸分离、纸箱重量、标签、托盘标记和批次识别检查

常问问题
What is a DIN 985 nylon lock nut?
DIN 985 is a metric hex lock nut with a nylon insert. The nylon ring creates prevailing torque on the bolt thread and helps resist loosening under vibration or movement.
Can DIN 985 nylon lock nuts be reused?
They may be removed and reinstalled in some non-critical applications, but locking performance can reduce after reuse. For safety or critical assemblies, new nuts are usually preferred.
Can DIN 985 nuts be used with Grade 8.8 carbon steel hex bolts?
Yes, if the nut grade is compatible with the bolt grade and the assembly requirement. Buyers should confirm nut grade, washer use, thread pitch, and tightening method.
Are nylon lock nuts suitable for high temperature applications?
Nylon inserts have temperature limits, so DIN 985 nuts should be checked carefully for high-heat assemblies. For high temperature use, all-metal lock nuts may be more suitable.
Which finishes are available for DIN 985 nylon lock nuts?
Common finishes include zinc plated, black oxide, plain stainless steel, nickel plated, Dacromet, and Geomet. Coating process and nylon insert compatibility should be confirmed before production.
我应该提供什么才能获得准确的报价？
Please provide the size list, thread pitch, grade, material, finish, nylon insert requirement, quantity, packaging method, inspection requirements, and any matching bolt or washer requirements.
