Description
Overview:
The Metric Nylon Insert Locking Nut, Size M14, is a hexagonal self-locking nut made from zinc‐plated steel with a nylon insert. The zinc plating helps resist corrosion in damp or outdoor conditions, while the nylon ring provides prevailing torque to stop the nut backing off under vibration. This makes it suitable for fastening tasks on construction equipment, agricultural machinery, garden tools, plant, and general workshop builds. Typical uses include engine mounts, guards, frames, brackets, wheels, and accessories where secure retention is important. The nut is manufactured to DIN 982 for consistent quality and fit on standard metric fasteners. Supplied in a pack of 50, it is a practical choice for maintenance teams, contractors, and DIY users who need reliable M14 locking performance.
Key Features:
- Self-locking nylon insert helps prevent loosening under vibration and shock loads
- M14 metric thread for use with standard M14 bolts and studs in mechanical assemblies
- Zinc-plated steel construction for durable corrosion resistance in indoor and outdoor use
- Complies with DIN 982 for predictable fit and compatibility with common tools
- Hex form for easy fitting and removal using standard spanners or sockets
- Helps maintain clamp load without separate threadlock in many applications
- Reusable a limited number of times; check prevailing torque after reassembly
- Pack of 50 for efficient workshop stock and site repairs
- Suitable for steel, painted, or coated assemblies where a consistent clamp is required
- Sensible choice for areas subject to vibration; avoid high-heat locations that can affect nylon
Typical Applications:
Fixing guards, covers, and brackets on mowers, generators, compactors, and mixers; securing engine mounts, chassis components, vibration isolators, PTO accessories, and frames; assembly of jigs, fixtures, and plant; maintenance tasks on agricultural implements and garden machinery where a secure M14 fastener is required.
Also known as:
Nylon insert nut, nyloc nut, nylon lock nut, self-locking nut, anti‐vibration nut, prevailing torque nut, stop nut, nylon-insert hex nut, vibration-resistant locknut.
