Value Collection MKCS08C0559MBPKG M8x1.25 Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MKCS08C0559MBPKG is a partially threaded socket cap screw with an M8x1.25 thread and a 55 mm length under head. Manufactured from Grade 12.9 alloy steel, it delivers high tensile strength suitable for demanding mechanical and structural fastening applications. The zinc-blue trivalent chromate finish provides corrosion resistance while meeting RoHS and REACH compliance standards. A 6 mm hex drive allows precise torque application with standard Allen keys or hex bits. This package contains 25 screws, making it a practical supply for production, maintenance, and repair work across industrial and mechanical trades.

This socket cap screw is suited for mechanical assemblies, machinery maintenance, equipment fabrication, and structural fastening where high-strength fasteners are required. The coarse M8x1.25 thread pitch and partial threading make it appropriate for through-bolt and clearance-hole applications. The DIN 912 and ISO 4762 standards ensure dimensional consistency across compatible tooling and hardware. Machinists, millwrights, maintenance technicians, and industrial assemblers commonly use this fastener in both OEM production and field repair contexts.

Installation Notes

Installation is performed by machinists, maintenance technicians, or industrial assemblers using a 6 mm hex key or bit driver. Ensure mating threads are clean and free of debris before installation. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints. Apply thread-locking compound or specified preload torque per the equipment manufacturer guidelines for the assembly being serviced.
