ASME Specification Hex bolts and hex cap screws feature a large fastener head for distributing clamping load. These fasteners are used at high tensions and temperatures. Cap screws have a washer face underneath the head and are used in precise applications. In Europe, a cap screw refers to a bolt-type fastener that is fully threaded, whereas a bolt is the part-threaded equivalent.
