Discover more about the Hexagon Nylon Locking Nuts range

Nylon Locking Nuts (also called Nyloc Nuts) are fitted with a polymer insert. The elastic Nylon insert of this component fits tightly against the fastener, and is designed to resist loosening. High Nylon Locking Nuts are an elongated variant of this component, which allow for greater thread contact and more secure fastenings.

For a more robust variant of this product, see Accu's Aerotight Locking Nuts range.


The metal section of a Nylon Locking Nut can be manufactured from A2 and A4 (Marine Grade) Stainless Steel. A full range of Aluminium and Titanium Nylon Locking Nuts are also available.

Metric Nylon Locking Nuts are manufactured according to DIN 985, and are available in metric sizes of between M2 and M20.
