UNF Nyloc Lock Nuts – Imperial

Description

These UNF nyloc nuts have a nylon insert secured toward the top of the nut. This reduces the nuts internal diameter and when tightened onto the thread of the fixing you’re using, the nylon polymer spreads elastically over the threads of the screw without cutting the thread into the nylon insert, acting as a secure and reusable locking mechanism. This action keeps the nut in position and makes it very resistant to vibration which can loosen normal nuts over time.

The Zinc plated steel provides corrosion resistance protection, whilst the nylon insert provides an extra seal against the leakage of oil, water, petrochemicals and other liquids.
