Holo-krome 76012 Hex Socket Cap Screw M3 X 0.50 Metric

Product Description

The HOLO-KROME 76012 is an M3 x 0.50 metric hex socket cap screw with an 8 mm length under head, manufactured from alloy steel with a black oxide finish. It is fully threaded and driven by a hex socket, making it a standard choice for precision mechanical assemblies, tooling fixtures, machine frames, and industrial equipment. The black oxide coating provides mild corrosion resistance and reduces light reflection in applications where surface finish matters. At material grade 12.9, this fastener delivers high tensile strength suitable for demanding clamping and fastening applications. Installation is performed by machinists, millwrights, and maintenance technicians working in fabrication and industrial settings.

This screw is suited for use in compact mechanical assemblies where a low-profile cap head and hex socket drive are required. Typical applications include CNC machine components, precision fixtures, robotics, and equipment panels where M3 thread pitch and an 8 mm under-head length are specified. The fully threaded design provides consistent thread engagement along the full length of the fastener, which is important in thin-material and close-tolerance applications. This screw conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards.

Key Features

• M3 x 0.50 metric thread with 8 mm length under head, fully threaded
• Grade 12.9 alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced glare
• Hex socket drive for precise torque application in confined spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard M3 x 0.50 metric hex socket cap screw per DIN 912 and ISO 4762, suitable for use in any application or assembly specifying this thread size, pitch, and under-head length in those standards.

Installation Notes

Installation requires an appropriately sized hex key or hex socket bit; use of the correct driver size prevents rounding of the socket drive recess. Ensure mating threaded holes or nuts are clean and free of debris before fastening. Follow the torque specifications provided in the equipment manufacturer documentation for grade 12.9 fasteners at M3 thread size, as overtightening can cause thread stripping or fastener failure in this small diameter. De-energize or lock out any equipment before servicing fastened assemblies per applicable safety procedures.
