Nord-Lock Washer 3/4 Inch (20.0mm x 30.7mm) in 316L Stainless (NL3/4SS), per pair

Nord-Lock washers, also known as wedge-locking washers, secure bolts with tension instead of friction. Working as a pair, these washers create a wedge-effect underneath the bolt head or nut so that the joint is prevented from loosening unintentionally. Nord-Lock washers are quick and easy to install and remove, and they are reusable. Supplied as a glued pair, they are appropriate for use in vehicles, for DIY and for watersport equipment. Most sizes are available in two external diameters: the smaller standard type listed here, and the larger SP type. Here you will find the specific imperial sizes; please refer to the data sheet and the metric section for other appropriate sizes.
