Nuts Steel Metric BZP BB934 Pack Quantity: 150
A Metal (metal insert) Nut is a torque prevailing nut that uses a metal insert located towards the top of the nut, reducing its inner diameter, which then deforms over the mating thread. This captures 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 insert, allowing the nut to be re-used.
The Metal insert is more durable than plastic or nylon inserts making it beneficial for use with products that are serviceable or require maintenance.
The nut can also be used to assist in sealing the bolt thread against seepage of oil, water, petrol, paraffin, and other liquids.
