Fitting Advice
Match both the diameter and thread form before fitting. UNF fasteners must be used with matching UNF nuts or tapped holes. Start threads by hand, then tighten using the correct imperial spanner or socket.
Browse our nuts and washers, or consult our thread data guide for help identifying threads.
