Description
Overview:
These Hex Socket Head Cap Screws are high‐strength fasteners in property class Grade 12.9, suitable for demanding mechanical assemblies. Made from high‐tensile alloy steel and finished in a chemical black treatment for added surface protection, they provide secure clamping where space is tight and a standard hex key (Allen key) is preferred over an external hex. Size M8 x 80 (8 mm diameter x 80 mm length) makes them a solid choice for brackets, housings, covers, and load‐bearing joints on construction equipment, workshop jigs, garden machinery, and automotive sub‐assemblies. The internal hex drive allows precise torque application and a tidy, flush finish. Supplied as a pack of 10 for convenient replenishment. Manufacturer Part Number (MPN): 903 0302 100PK.
