M18 Thin Nyloc Hex Nut | 2.50mm Pitch | DIN 985 | A4-80 Stainless Steel
Designed for general bolted joints where resistance to loosening is required, this M18 nylon insert locknut combines a metal hex nut body with a nylon insert to help resist loosening caused by vibration or repeated movement. The DIN 985 thin pattern keeps the overall height to 18mm while maintaining the specified 2.50mm metric thread. The A4 stainless steel construction provides enhanced corrosion resistance for suitable outdoor, coastal and marine fastening applications.
What Are DIN 985 Nyloc Nuts?
DIN 985 Nylon Lock Nuts use a polymer insert above the metal thread to create resistance against the mating bolt. The nut body remains metal while the nylon insert provides the locking action which makes these fasteners useful in vibration-prone mechanical assemblies.
This DIN 985 style sits within our wider self-locking hex nuts range. For applications that require a taller nylon insert nut, our high nylon lock hex nuts provide the DIN 982 alternative.
Common Applications
- Machinery: Helps secure bolts on guards, brackets and equipment where vibration could loosen a conventional nut.
- Automotive Assemblies: Provides a locking nut for suitable brackets, panels and mechanical fixings exposed to movement.
- Electrical Equipment: Secures compatible bolts in control panels, enclosures and equipment frames.
- General Engineering: Provides a reusable locking fastener for fabricated assemblies, maintenance work and mechanical builds.
