Hex Head Cap Screws & Hex Bolts
Hex head cap screws or hex bolts have a hexagonal head that is designed for a ratchet or spanner torque wrench. This allows for tightening of the screw. Hex cap screws or hex bolts are manufactured with different grades, finishes, sizes, and specifications depending on application. A washer is commonly used under the head of the hex cap screw and the chamfered end and a nut is used matching up with the thread type of the hex bolt to exact specifications. These fasteners are mostly used in construction, machine parts, and maintenance.
