Value Collection MKCS03C0309MBPKG M3x0.5 Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION MKCS03C0309MBPKG is a partially threaded socket cap screw with an M3x0.5 thread size and a 30 mm length under head. Built from alloy steel to material grade 12.9, it delivers high tensile strength suitable for demanding mechanical assemblies. The zinc-blue trivalent chromate finish provides corrosion resistance and meets RoHS and REACH compliance standards. Driven by a 2.5 mm hex key, this fastener is suited for precision equipment assembly, machine frames, tooling fixtures, and other applications where a compact cap head profile is required. This package contains 50 pieces.

This socket cap screw is intended for use in mechanical, industrial, and equipment assembly applications where a high-strength, small-diameter fastener is needed. The M3x0.5 coarse right-hand thread and partially threaded shank make it appropriate for through-hole and clearance-hole installations in metal components. Typical installers include machine builders, millwrights, maintenance technicians, and equipment assemblers working with light structural and precision mechanical assemblies.

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring DIN 912 or ISO 4762 compliant M3x0.5 socket cap screws with a 30 mm length under head.

Installation Notes

Installation requires a 2.5 mm hex key or Allen driver. Power down and de-energize any equipment before fastener service. Do not exceed the rated torque range for grade 12.9 M3 fasteners as specified by the equipment manufacturer. Follow applicable mechanical assembly standards and workplace safety protocols when working with high-strength fasteners.
