    The Allstar Performance Countersunk Bolt Kit in Blue features 1/4-20in thread, 1in long Allen head bolts paired with color-coded plastic countersunk washers and lock nuts. The washers are specially designed to let the socket-head bolts install flush with the surface for a smooth, finished look. Bolts are zinc-oxide plated steel for added corrosion resistance. Common uses include mounting roofs, side skirts, and spoilers, and replacing sharp-edged fasteners inside the cockpit. Each kit includes a matched set of Blue plastic washers, bolts, and nyloc nuts.

    Set of 10.

    Compatibility

    This is a universal, color-coded fastener kit for racing body panels — sized by thread (1/4-20in), length (1in), and pack quantity (10), not by vehicle make or model. Choose Blue to match or contrast with existing color-coded hardware on the car.
