Value Collection MKCS20C0409MB M20x2.5 Socket Cap Screw

Product Description

The VALUE COLLECTION MKCS20C0409MB is a fully threaded socket cap screw with an M20x2.5 thread size and a 40 mm length under head. Built from Grade 12.9 alloy steel, it delivers high tensile strength for demanding mechanical and structural fastening applications. The zinc-blue trivalent chromate finish provides corrosion resistance while meeting RoHS and REACH compliance requirements. A 17 mm hex drive and a 30 mm head diameter conform to DIN 912 and ISO 4762 fastener standards. This screw is installed by millwrights, maintenance technicians, and mechanical contractors where high-strength fastening is required in assemblies subject to significant load or vibration.

This socket cap screw is suited for use in industrial machinery, structural steel assemblies, hydraulic and pneumatic equipment frames, and general mechanical fabrication. The coarse M20x2.5 thread pitch and full threading along the shank length allow engagement across the complete fastened joint. Right-hand thread direction matches standard tooling and installation practices. It is sold individually and is appropriate wherever a DIN 912 or ISO 4762 M20 socket cap screw is specified.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• Fully threaded shank with M20x2.5 coarse right-hand thread
• DIN 912 and ISO 4762 fastener standard compliance for dimensional interchangeability
• Zinc-blue trivalent chromate finish provides corrosion resistance without hexavalent chromium
• RoHS and REACH compliant finish coating
• 17 mm internal hex drive accepts standard hex keys and socket drivers

Compatibility

Designed as a DIN 912 and ISO 4762 compliant M20x2.5 socket cap screw, suitable as a direct replacement or new installation fastener in any application specifying an M20x2.5 coarse-thread socket head cap screw at this length.

Installation Notes

Installation requires a 17 mm hex key or hex socket driver. Power down or de-energize any equipment and relieve all pressure or load from the assembly before removing or replacing fasteners. Follow applicable equipment manufacturer torque specifications for Grade 12.9 M20 fasteners; do not rely on generic values. Inspect threads and mating surfaces for damage before installation to ensure full thread engagement.
