Selecta LN3816J 3/8-16 Nylon Insert Lock Nut Zinc 100/jar

Product Description

The SELECTA LN3816J is a 3/8-16 nylon insert lock nut finished in zinc plating for corrosion resistance. The nylon insert creates a prevailing-torque locking action that resists vibration-induced loosening without requiring a secondary locking element. Manufactured from steel with a zinc plated finish, this nut is suited for general mechanical fastening applications across HVAC, plumbing, electrical, and light structural assemblies. Each jar contains 100 nuts, making it a practical bench-stock item for service technicians and contractors who run through standard 3/8-16 hardware regularly.

This lock nut is appropriate for residential and commercial trade applications wherever a 3/8-16 threaded bolt or stud requires a secure, vibration-resistant connection. Common use cases include equipment mounting, panel fastening, pipe hanger assemblies, and equipment support structures. The zinc plated finish provides a degree of corrosion protection suitable for dry and mildly humid indoor environments. The jar packaging keeps hardware organized and accessible on a service vehicle or shop bench.

Compatibility

Designed as a standard 3/8-16 UNC nylon insert lock nut compatible with any 3/8 inch diameter, 16 threads-per-inch bolt or threaded stud conforming to standard unified coarse thread specifications.

Installation Notes

Nylon insert lock nuts are installed by hand-starting the nut onto the bolt thread and tightening with the appropriate wrench to the fastener specification required by the assembly. Power down or de-energize any equipment before fastening hardware in electrical or mechanical enclosures. Note that nylon insert lock nuts are generally considered single-use fasteners, as the locking torque of the nylon insert diminishes with repeated removal and reinstallation. Follow applicable codes and equipment manufacturer guidelines for fastener torque requirements.
