About

A Flange Nyloc (nylon insert) Nut is a torque prevailing nut, which uses a plastic / nylon insert located toward the top of the nut reducing its inner diameter, which then deforms over the mating thread, capturing the bolt or screw providing a locking feature causing resistance or prevailing torque keeping the nut locked in position and resistant to vibration.  This design feature of the Flange Nyloc (Nylon Insert) nut means that the screw threads do not cause damage to the plastic / nylon section allowing the nut to be re-used, although the locking feature will deteriorate after persistent re-use.

The Flange Nyloc (nylon insert) nut is an economic locking nut and is ideal in applications where vibration or motion could loosen or undo the nut.  The Flange Nyloc (nylon insert) nut can also be used to assist sealing the bolt thread against seepage of oil, water, petrol, paraffin and other liquids.

Flange Nyloc (nylon insert) nuts can be used in environments with relatively high temperatures where they can retain their locking ability up to 121°C. 
The Nyloc nut is available in a variety of materials and finishes.
