The hex head bolt is a common fastener in construction and machine assembly. The bolt head is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the bolt to your exact specifications.

Hex head bolts are typically used to create a bolted joint, in which a threaded shaft exactly fits a corresponding tapped hole or nut.
