hex bolt
Wrench-turned threaded fastener
A hex bolt is a fastener with a threaded shaft and a six-sided head designed to be tightened with a wrench or socket.
The hexagonal head provides flat surfaces for gripping, allowing more torque than slotted or Phillips-head screws.
Hex bolts are standard in construction, machinery, and automotive work: The mechanic replaced the hex bolts on the engine mount.
