DIN931 Half Thread Stainless Steel External Hex Head Screw

Hexagon head cap screws, also called hex bolts or hex head cap screws, are threaded fasteners with a six-sided head. They are installed with a wrench or a socket. Compared to other fasteners, hex head cap screws provide a larger surface-bearing area for better clamping. Hex bolts are well-suited for OEM applications, construction projects, infrastructure, and other uses that require tight tolerances

Stainless steel bolts are generally available in bright self finish. Stainless steel bolts are polished or ground after forging and other activities to provide them with a bright finish. Sometimes customers require stainless steel bolts to be Xylan coated to provide an added layer on top of the surface bright finish.
