Collection: Metric & Imperial Fasteners - Bolts, Nuts & Washers

Browse metric and imperial fasteners for automotive repairs, restoration, fabrication and workshop projects. The range includes bolts, socket-head and button-head screws, countersunk screws, hex nuts, locking nuts, washers, rivet nuts and selected panel fasteners.

Match the exact thread and dimensions

Check the thread diameter and metric pitch or imperial threads per inch against the mating component. UNC and UNF options are listed throughout the range; do not assume fasteners with the same nominal diameter share the same thread.

Confirm the required length, threaded section, head style and tool access. For washers, check inside diameter, outside diameter and thickness. For rivet nuts and panel fasteners, confirm hole size, material thickness, grip range and installation-tool requirements for the exact item.

Choose the specified grade and material

Listings include selected zinc-plated steel and stainless steel options, with grades and material details varying by product. Match the component manufacturer's specified fastener grade, material, finish and locking method rather than selecting by appearance or size alone. Do not assume stainless steel is a direct replacement for a specified high-tensile steel fastener.

Check quantity and installation requirements

Refer to each listing for its product code and whether it is sold individually or as a pack. Where pitch, grade or another essential detail is not shown, contact SS Racetech before ordering.

Follow the component and fastener manufacturer's installation instructions, including torque, lubrication and replacement requirements. For load-bearing or safety-critical assemblies, confirm the exact specified hardware with the component manufacturer or your qualified installer.
