1/4 Non-Serrated Flange Screw (ASME B18. 2.1)

Frame Bolts are hex washer head bolts with a flat washer bearing surface. They are made from high-alloy steel, and commonly used on truck frames, hence the name frame bolt. The flange eliminates the need for washers. They are covered under ASME Standard B18.2.1
