DIN931 Half Thread Stainless Steel External Hex Head Screw မြန်မာ

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
