Storage
The complete set comes in a plastic storage box with dividers and a clip-down lid, helping keep the different bolt lengths, nuts and washers separated and easy to find.
Measuring and Fitting
Bolt lengths are measured from beneath the hexagon head to the end of the bolt. Choose a length that provides sufficient engagement with the matching nut or tapped hole.
Match the 5/16"-24 UNF thread, start threaded components by hand and tighten with a correctly fitting imperial spanner or socket. When fitting a Nyloc nut, ensure the bolt passes through the nylon locking insert.
