Value Collection MKCS03C0129MBPKG M3x0.5 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION MKCS03C0129MBPKG is a fully threaded M3x0.5 socket cap screw designed for precision fastening in mechanical assemblies, equipment fabrication, and maintenance applications. Built from grade 12.9 alloy steel, it delivers high tensile strength in a compact form. The hex socket drive accepts a 2.5 mm hex key for controlled torque application in tight spaces. A zinc-blue trivalent chromate finish provides corrosion resistance and meets RoHS and REACH compliance requirements. These screws ship in a package of 100, making them practical for shop stock or batch assembly work. Licensed tradespeople and production technicians working in HVAC, electrical, or mechanical service will find these screws suited to standard metric fastening tasks.

These M3x0.5 socket cap screws are appropriate for residential and light commercial equipment assembly, fixture mounting, and OEM-style component replacement where a metric coarse-thread fastener with a low-profile cap head is required. The 12 mm length under head and 5.50 mm head diameter are consistent with DIN 912 and ISO 4762 standards, making them interchangeable with other fasteners built to those specifications. The right-hand coarse thread pitch is the standard for M3 applications across most mechanical and electrical equipment platforms.

• Package quantity of 100 units for shop stock or production use

Compatibility

Designed as a standard DIN 912 and ISO 4762 compliant M3x0.5 socket cap screw suitable for general metric fastening applications in mechanical, electrical, and HVAC equipment assemblies.

Installation Notes

Installation requires a 2.5 mm hex key or hex bit driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before fastener service per applicable safety codes. Do not substitute imperial-size hex drivers, as doing so may damage the socket recess.
