Stainless Steel A4 Nylock Nut M8

Stainless Steel A4 Nylock Nut M8
Part Number: LSSNYN8


A Nylock Nut uses a nylon insert which acts as a locking mechanism.

The nylon insert locks the Nut in two ways.
First, it forces the bottom face of the screw threads against the top face of the Nut threads, increasing the friction between the two.
Second, the nylon applies a compressive force against the screw itself.
Nylon inserts are less damaging to threads however the nylon can deteriorate with numerous re-uses.
Another feature of a Nylock Nut is that it can help to lock out moisture preventing corrosion and sealing the bolt thread.

Supplied here individually.

Material Information 

Stainless Steel

Manufactured from A316 stainless steel. A316 stainless steel has a minimum chromium content of 16.5% and contains elements of carbon, molybdenum, silicon, phosphorus, sulphur, nickel, manganese and iron, all of which add properties of formability, strength, weldability and enhanced corrosion resistance. All of the fasteners are highly polished to a mirror-like finish.
