HT Allen Hex Socket Button Head Screw:M12 x 75 - ISO 7380/12.9/Black/Half Thread

This high-tensile steel fastener is an M12 x 75 mm Allen hex socket button head screw designed for high-strength mechanical assemblies. Manufactured to ISO 7380 standards with a property class 12.9 rating, it delivers superior load-bearing capacity suitable for demanding industrial applications. The black surface finish provides a durable, corrosion-resistant coating, while the half-thread design allows the unthreaded shank to add structural integrity between the joint faces. Buyers select this specification when a combination of high shear strength, compact head profile, and partial threading is required for precise alignment. Selection is defined by the M12 nominal diameter, 75 mm nominal length, and the specific 12.9 grade, ensuring compatibility with high-stress engineering requirements.
