UNF Nyloc Nut Assortments
Our UNF Nyloc Nut assortments provide a convenient selection of Unified National Fine (UNF) thread sizes in self-locking nylon insert nuts.
Designed for use with UNF bolts and set screws, these fine thread lock nuts resist loosening under vibration by creating friction against the mating thread through an integrated nylon insert collar.
Widely used in automotive, performance engineering, machinery and specialist equipment applications, UNF Nyloc nuts provide secure fastening where fine pitch threads and improved clamping precision are required.
Available in materials such as zinc plated steel or stainless steel where applicable, these assorted kits are supplied in organised compartment storage boxes for easy workshop use.
Part of our Assorted Fastener Sets range, these kits are ideal for engineers and service professionals working with imperial fine thread fasteners.
