Collection: Cap Screws / Hex Bolts

Hex cap screws and hex bolts are two threaded fasteners with hexagonal heads, designed for different purposes. Hex cap screws feature tighter body diameter tolerances, a washer face under the head, and are typically installed by turning the head into a tapped hole. Hex bolts, on the other hand, have larger body diameter tolerances, no washer face, and are installed by turning a nut to secure the fastener.
