Hardware & Fasteners

Match the fastener to the job

Start with what the part has to do. Bolts and nuts suit joints that need a nut or tapped hole, while washers spread load or protect a surface. Check thread size, pitch, length and material shown on the listing. Assortment kits are handy for a workshop drawer, but confirm the sizes included before assuming your size is covered.

Clips, pins and trim fasteners

Retaining hardware is often specific to its location, so compare the shape and dimensions with the part you are replacing. Circlips, split pins, R-clips and hitch pins each lock in a different way. For interior panels and trim, body clips and trim fasteners come in many head and stem styles, and kits may mix several types. Check whether screws are included with the clips.

Sealing, joining and securing

Hose clamps, O-rings and grommets are sized by diameter or clamping range, so measure before buying. Adhesives, sealants, gasket makers and thread lockers are chosen by the surfaces and fluids involved, so read the listing for intended materials and any stated temperature or fluid information. Hose clamps and fittings are listed by size range, which is the first detail to compare.
