The Allstar Performance Countersunk Bolt Kit in Silver 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 Silver plastic washers, bolts, and nyloc nuts.
Set of 10.
