Wilwood 230-10420 Flat Head Cap Screw 3/8-24 x 1.50" Caliper Bracket Bolt

The Wilwood 230-10420 is a high-strength flat head cap screw designed for use in Wilwood disc brake system assemblies. Featuring a 3/8-24 thread x 1.50" length flat head profile, this bolt is engineered for caliper mounting bracket applications where a low-profile, countersunk fastener is required for proper clearance and a flush seating surface.

Wilwood flat head cap screws are manufactured from high-strength alloy steel or stainless steel, with plating methods selected based on the specific application requirements. The flat head design allows the bolt to sit flush with or below the mounting surface, reducing interference with surrounding components in tight brake system packaging.
