UNF Thin Lock Nut Assortments

Our UNF Thin Lock Nut assortments provide a convenient selection of Unified National Fine (UNF) thread sizes in a reduced height pattern.

Also known as half nuts or thin nuts, these fasteners are commonly used alongside standard full height nuts to create a locking effect, helping to prevent loosening in vibration-prone applications.

Manufactured to UNF thread specifications, these fine thread thin nuts are widely used in automotive, performance engineering, machinery and specialist equipment where precise adjustment and secure fastening are required.

Supplied in organised compartment storage boxes, these assorted kits ensure commonly used UNF sizes are readily available for workshop, maintenance and trade use.

Part of our Assorted Fastener Sets range, these kits are ideal for engineers and service professionals working with imperial fine thread systems.
