Value Collection MKCS03C0109MBPKG M3x0.5 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION MKCS03C0109MBPKG is an M3x0.5 socket cap screw supplied in a 100-piece package. Manufactured from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, this fastener delivers high tensile strength and corrosion resistance in a compact metric format. The screw features a socket head driven by a 2.5mm hex key and is fully threaded under the head with a 10mm length. It conforms to DIN 912 and carries RoHS and REACH compliance, making it suitable for precision mechanical assemblies across industrial and commercial applications.

This fastener is commonly used in machine component assembly, fixture fabrication, tooling, and equipment maintenance where a low-profile socket head and high clamping force are required. The M3 coarse thread pitch and 10mm length suit tight-clearance fastening tasks in light machinery, enclosures, brackets, and mounting plates. Maintenance technicians, machinists, and fabricators working on metric-dimensioned equipment regularly stock this size for scheduled and unplanned repair work.

Compatibility

Designed as a standard DIN 912 metric socket cap screw for use in any M3x0.5 coarse-thread tapped hole requiring a 10mm fully threaded fastener.

Installation Notes

Installation is performed with a 2.5mm hex key or Allen driver; use calibrated torque tools when the application specifies a torque value for grade 12.9 fasteners. Inspect mating threads for cleanliness and proper pitch before installation to avoid cross-threading. Grade 12.9 fasteners are not recommended for welding or heat-affected zones. Follow applicable mechanical or equipment manufacturer specifications for torque and thread engagement requirements.
