The Value Collection MP42101 is a fully threaded hex head cap screw designed for general-purpose metric fastening applications. Built to Grade 8.8 steel, this screw delivers reliable tensile strength and is finished with a zinc plating that provides basic corrosion resistance in typical shop, industrial, and mechanical environments. The M12 x 1.75 thread profile and 25 mm length under head make it a standard metric fastener widely used in machinery assembly, structural bracketing, and equipment maintenance. The 19 mm hex drive is compatible with standard metric wrenches and sockets. Compliance with DIN 933 and ISO 4017 ensures dimensional consistency across batches.
This cap screw is suited for residential and commercial mechanical applications where metric fasteners are specified. Common install scenarios include machine frames, industrial equipment, automotive components, and structural assemblies requiring a fully threaded M12 fastener. The zinc plating makes it appropriate for dry to mildly humid indoor environments. Sold in a package quantity of 25 pieces, this part suits both single-job use and bench stock replenishment.
Designed as an OEM-style replacement or general-stock metric fastener for machinery, equipment, and structural assemblies requiring an M12 x 1.75 fully threaded hex head cap screw per DIN 933 and ISO 4017 specifications.
Installation is performed with a standard 19 mm metric wrench or socket driver. Ensure mating threads are clean and free of debris before driving the fastener. Follow applicable torque specifications for Grade 8.8 M12 fasteners as published in the relevant equipment service manual or industry fastener standards. Do not mix metric and standard fasteners in the same assembly.
