Value Collection MKCS03C0209MBPKG M3x0.5 Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION MKCS03C0209MBPKG is an M3x0.5 socket cap screw engineered for precision fastening in mechanical assemblies, tooling fixtures, and equipment fabrication. Manufactured from alloy steel to material grade 12.9, this fully threaded fastener delivers high tensile strength suitable for demanding clamping applications. The zinc-blue trivalent chromate finish provides corrosion resistance while meeting RoHS and REACH compliance requirements. Each screw measures 20 mm under the head and accepts a 2.5 mm hex key drive. This package contains 50 screws, making it practical for shop stock or field service kits. Machinists, millwrights, and maintenance technicians are the primary users of this fastener type.

These socket cap screws are suited for use in tight-clearance applications where a flush or recessed fastener head is required. The coarse right-hand thread pitch of 0.5 mm engages standard M3 tapped holes in steel, aluminum, and cast components. Typical installation scenarios include machine guards, motor mounts, bracket assemblies, panel hardware, and precision equipment frames in both industrial and light commercial environments. The 50-piece packaging supports bench stock replenishment and job lot requirements.

Key Features

• Grade 12.9 alloy steel construction for high-strength clamping and shear resistance
• Fully threaded M3x0.5 coarse right-hand thread for consistent engagement in standard M3 tapped holes
• 2.5 mm hex key (Allen) drive for socket wrench or T-handle installation in confined spaces
• Zinc-blue trivalent chromate finish for corrosion resistance without hexavalent chromium compounds
• RoHS and REACH compliant per trivalent chromate process
• Conforms to DIN 912 and ISO 4762 fastener standards
• 50-piece package for bench stock or project quantities

Compatibility

Designed for use in any application requiring a DIN 912 or ISO 4762 compliant M3x0.5 socket cap screw with a 20 mm length under head. Fits standard M3 tapped holes in steel, aluminum, and similar materials.

Installation Notes

Installation is performed with a 2.5 mm hex key or socket bit driver. De-energize and lock out any equipment before fastener service per applicable safety procedures. Do not mix grade 12.9 fasteners with lower-strength hardware in the same joint without verifying load requirements with a qualified engineer. Thread engagement depth should meet standard recommendations for the base material being used.
