Hex Head Cap Screws


Custom & Standard Hex Head Cap Screws (Hex Bolts) | U-Bolt-It

What is a Hex Head Cap Screw?

Hex bolts, commonly referred to as hex head cap screws, are rugged industrial fasteners featuring a distinctive hexagonal (six-sided) head. Unlike standard bolts, hex cap screws are manufactured to tighter tolerances and feature a smooth washer surface directly under the head. This specific design creates a superior seal and more uniform clamping force when installed.
