Bolt

A standard steel or metallic silver-gray hex-head bolt shown in clean technical side view, with a flat six-sided hexagonal head and a flat bearing surface underneath. A straight cylindrical shank extends from the head, typically with a smooth unthreaded grip section and a partially threaded end section, though it may also appear threaded along most of its length. The threads are clearly defined as evenly spaced helical V-profile ridges. The metal surface has an industrial finish, and the free end is flat or slightly chamfered. Overall proportions match a typical machine bolt or standard industrial fastener.
