Value Collection MKCS05C0309MBPKG M5x0.8 Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION MKCS05C0309MBPKG is an M5x0.8 socket cap screw designed for secure mechanical fastening in demanding trade and industrial applications. Manufactured from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, this screw delivers high tensile strength combined with corrosion resistance. The partially threaded shank provides precise clamping force and accurate joint alignment. The 4 mm hex drive accepts a standard internal hex key for reliable torque application. This package contains 50 screws, making it suitable for production, maintenance, and repair work across HVAC equipment assembly, electrical enclosures, plumbing fixtures, and general mechanical installations.

This M5x0.8 partially threaded socket cap screw is suited for residential and commercial mechanical assemblies where a compact, high-strength fastener is required. The coarse right-hand thread and DIN 912 and ISO 4762 standards make it a widely compatible choice for equipment panels, brackets, pump housings, fan assemblies, and structural mounting hardware. The trivalent chromate finish meets RoHS and REACH compliance requirements, making it appropriate for use in environmentally regulated installations and equipment. The 50-count package quantity supports both single-job use and stocked shop inventory.
