Hexagonal Head Screws / Bolts

A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. Bolts are often used to make a bolted joint. This is a combination of the nut applying an axial clamping force and also the shank of the bolt acting as a dowel, pinning the joint against sideways shear forces.

Bolts are externally threaded fasteners designed for insertion through holes in assembled parts. They’re usually meant to be tightened or released by torquing a nut (ASME B18.2.1). Delight Industrial’s provides high quality, flexible packaged Hex bolts
