Nyloc Nuts
NyLoc Nuts or Nylon Insert Nuts are a type of Lock Nut containing a nylon collar which elastically deforms when a threaded fastener is inserted, causing a frictional locking action, and are 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 low carbon, high tensile steels. Nyloc nuts can be re-used but care must be taken, if perhaps where the failure of a nut would be critical, its locking operation must be assured before use.
