Sirius 12.9 Grade Socket Head Cap Screws M8 200mm Pack of 1

Designed for high-stress applications, this M8 socket head cap screw delivers exceptional tensile strength and durability thanks to its premium grade 12.9 alloy steel construction. Whether you are securing machinery components, automotive assemblies or heavy-duty fixtures, the black finish provides corrosion resistance while the precisely engineered hex socket ensures reliable torque transfer during installation. The screw is fully threaded for the first 40mm, allowing versatile engagement in shallow holes, and switches to a partial thread for the remaining length, giving you a strong, unthreaded shank for superior shear resistance in deeper fastening points. Ideal for engineers, mechanics and DIY professionals who demand uncompromising performance.
