A Flange Nyloc (nylon insert) Nut to DIN 6926 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 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 nylon insert nut is an economic locking nut and is ideal in applications where vibration or motion could loosen or undo the nut. It can also be used to assist sealing the bolt thread against seepage of oil, water, petrol, paraffin and other liquids. Also suitable for use in environments with relatively high temperatures where the locking ability can be retained up to 121°C.
