Hex bolts and hex cap screws both have a six-sided hexagon shaped head and are commonly referred to as the same bolt, but they are different. Hex cap screws have a washer face under the head with external threads designed to be inserted in pre-tapped holes so do not require a nut. Hex bolts also have external threads and are sometimes inserted into pre-drilled holes and usually require the use of a nut to tighten. Hex bolts are both fully threaded and partially threaded. Partially threaded hex bolts have a smooth shank section below the head before the threads which is more prominent the longer the hex bolt. Fully threaded hex bolts are commonly referred to as tap bolts.
