Nuts Nylon Insert Metric BB933 Pack Quantity: 115
A Nyloc (nylon insert) Nut is a torque prevailing nut which uses a plastic/nylon 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 plastic/nylon section allowing the nut to be re-used although the locking feature will deteriorate after persistent re-use.
The Nyloc nut is an economic locking nut and ideal in applications where vibration or motion could loosen or undo the nut.
The nut can also be used to assist sealing the bolt thread against seepage of oil, water, petrol, paraffin and other liquids.
