This product is an M12 x 75mm socket head cap screw (metric), driven by a 10mm hex bit. It is intended for fastening applications where a compact cylindrical head and a hexagon internal drive are required, typically used to clamp components together in machinery, jigs and fixtures, assemblies and maintenance work.

Technically the fastener is an M12 nominal diameter with a 75mm length and standard ISO metric coarse thread (pitch 1.75mm). The head is a cylindrical socket head (socket cap screw) to ISO 4762 / DIN 912 with a 10mm hexagon socket drive. Typical material and finish options are carbon steel to property class 10.9 with a zinc-plated finish for improved corrosion protection, or stainless steel A2/A4 to ISO 3506 where enhanced corrosion resistance is required. Threads comply with ISO metric thread tolerances (ISO 261 / ISO 965) and the product is suitable for use where the strength and clamping characteristics of a high tensile fastener are needed.

Common applications include mechanical assemblies, plant and equipment maintenance, automotive and heavy engineering where high clamp loads and compact head profiles are needed. Because the drive is a 10mm hex socket, the screw is compatible with standard 10mm hex keys, Allen drivers, bit sockets and powered hex bit holders, allowing controlled torque application and repeatable assembly.

Key benefits of choosing the M12 x 75mm socket cap screw with a 10mm hex drive are the high tensile capacity when supplied in grade 10.9, good resistance to loosening under vibration when correctly torqued, and the availability of corrosion-resistant stainless variants for use in damp or corrosive environments. The standardised drive and head form make it compatible with common tooling and replacement parts across industries.
