What' s Bolt?

A bolt is a type of fastener with external threads, designed to be inserted through holes in assembled parts. Its main job is to work with a nut to clamp everything together securely.

Structurally, a bolt has two key parts: a head (shaped for tools like a wrench) and a threaded shank. Unlike a screw, which often threads directly into a material, a bolt typically requires a nut to lock it in place. When you tighten the nut, the bolt stretches slightly, creating a strong clamping force that holds the parts together.

Bolts come in many types—hex head is the most common—and are made to strict standards (like ISO or DIN) for strength and reliability. They’re essential in everything from car engines to building frames, offering both strength and the convenience of being easy to take apart when needed.
