Nylon Insert Nuts – Type P – UNF

A Nylon Insert Nut is a torque prevailing nut, which uses a nylon insert inside of the nut to reduce 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 is the higher profile (Type P) variant with more available thread engagement and is typically fitted with a spanner or ratchet with socket.
