Value Collection MKCS08C1209MBPKG M8x1.25 Socket Cap Screw 5pk

Product Description

The VALUE COLLECTION MKCS08C1209MBPKG is a partially threaded socket cap screw designed for high-strength mechanical fastening in industrial, HVAC, plumbing, and general trade applications. Built from Grade 12.9 alloy steel, this screw delivers exceptional tensile strength suitable for demanding assemblies. The M8x1.25 coarse thread and 120 mm length under head make it well suited for medium-to-large fastening tasks where partial threading is required to create a firm clamping zone. Drive engagement is via a 6 mm internal hex socket. Each package contains 5 screws. Licensed trades and maintenance professionals reach for this fastener when precision fit and material integrity matter.

This socket cap screw is appropriate for use in mechanical assemblies, equipment mounting, HVAC component installation, and structural fastening scenarios requiring a right-hand coarse-thread M8 fastener. The zinc-blue trivalent chromate finish provides corrosion resistance and meets RoHS and REACH compliance standards, making it suitable for both indoor and environmentally controlled outdoor installations. Professionals working on commercial or industrial equipment will find the Grade 12.9 rating delivers the torque capacity needed for tight-tolerance joints.
