Nyloc Nuts

Nyloc nuts or nylon insert nuts are a type of lock nut containing a nylon collar which deforms when a threaded fastener is inserted, causing a frictional locking action. This design of nut is very popular. Referred to worldwide as nyloc nuts we have several variants in metric and imperial sizes, with A2 and A4 grades of stainless steel as well as zinc plated steels. Nyloc nuts can be re-used but care must be taken, particularly in strength critical applications, that its locking operation is assured before use.
