UNF Nut Assortments
Our UNF Nut assortments provide a convenient selection of commonly used Unified National Fine (UNF) thread sizes for imperial fastening applications.
Designed for use with UNF bolts and set screws, these fine thread nuts are widely used in automotive, performance engineering, machinery and specialist equipment where higher thread engagement and improved resistance to loosening are required.
Manufactured to UNF thread specifications and available in materials such as zinc plated steel or stainless steel where applicable, these nuts deliver reliable clamping performance across a wide range of environments.
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.
