Wholesale DIN931 Half Thread Black Hex Bolt Grade 8.8

Hex head bolts are designed to secure objects within or against other objects for a non-loosening hold. Applications for a hex bolt include fastening steel to steel, wood to wood, and other materials found on construction for projects such as highway structures, bridges, and buildings.

The Hex bolts allow for greater torque than traditional circular screws and tend to spin as you tighten and loosen them, making the need to hold with a wrench or socket. Hex bolts are commonly installed and removed with socket wrenches.

Hex head bolts come in two styles fully threaded and partially threaded. A fully threaded hex head bolt is used when it is matched up to a fully threaded hole. Partially threaded bolts are more rigid and have an unthreaded area under their head to allow for more holding strength when force is applied to the structure being secured.
