Русский DIN 985 nylon lock nuts manufacturer
XZ Fastener supplies DIN 985 nylon lock nuts for machinery, automotive equipment, electrical cabinets, brackets, furniture hardware, and vibration-sensitive assemblies. DIN 985 is a prevailing torque hex lock nut with a non-metallic nylon insert that helps resist loosening under vibration and repeated movement. Carbon steel and stainless steel options can be supplied with zinc plated, black oxide, plain, and other finishes according to order requirement. Buyers can specify thread size, grade, insert material, finish, quantity, packaging, matched bolts, washers, and inspection requirements.
Quick Specs
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 anti-loosening fasteners before finalizing the assembly.
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.
For a related product reference, see XZ Fastener’s prevailing torque lock nut page and compare the locking method with nylon insert requirements.

Material and Grade Explanation
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 nut grade and bolt torque matching.
Surface Finish Selection Guide
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.
| Finish | Suitable Use | Purchasing Consideration |
|---|---|---|
| Zinc plated | General machinery, equipment assembly, indoor stock | Common finish for carbon steel nylon lock nuts and compatible metric hex head bolts. |
| أكسيد أسود | Machinery interiors and black appearance requirements | Usually requires oil or additional protection for corrosion resistance; can be matched with black oxide DIN 933 bolts. |
| Plain stainless steel | Moist environments, food equipment, light marine exposure depending on grade | A2 and A4 stainless options should be selected according to corrosion conditions. |
| Dacromet or Geomet | Outdoor equipment and corrosion-sensitive assemblies | 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. |

Manufacturing and Quality Control
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.
- Across-flats width, nut height, chamfer, and thread depth checks
- Go/no-go thread gauge inspection for metric thread compatibility
- 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
- Size separation, carton weight, label, pallet mark, and batch identification checks
For assembly inspection details, buyers can review XZ Fastener’s inspection guide for anti-loosening fastener assemblies.

أسئلة متكررة
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.
What should I provide for an accurate quotation?
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.
