DIN Produttore di dadi di bloccaggio in nylon 985
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.

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 dispositivi di fissaggio anti-allentamento 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.

Spiegazione del materiale e del grado
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 corrispondenza del grado del dado e della coppia dei bulloni.
Guida alla selezione della finitura superficiale
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.
| Finisci | Uso adatto | Considerazione sull'acquisto |
|---|---|---|
| Zincato | Macchinari generali, assemblaggio di attrezzature, magazzino interno | Common finish for carbon steel nylon lock nuts and compatible metric hex head bolts. |
| Ossido nero | Interni dei macchinari e requisiti di aspetto nero | Usually requires oil or additional protection for corrosion resistance; can be matched with black oxide DIN 933 bolts. |
| Acciaio inossidabile normale | Moist environments, food equipment, light marine exposure depending on grade | A2 and A4 stainless options should be selected according to corrosion conditions. |
| Dacromet o Geomet | Attrezzature per esterni e gruppi sensibili alla corrosione | 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. |

Produzione e controllo qualità
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.
- Controlli della larghezza del piano, dell'altezza del dado, dello smusso e della profondità della filettatura
- 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
- Controlli relativi alla separazione delle dimensioni, al peso del cartone, all'etichetta, al contrassegno del pallet e all'identificazione del lotto

FAQ
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.
Cosa devo fornire per un preventivo accurato?
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.
