Value Collection -42704-2 Hex Socket Cap Screw M3 X 0.50

Product Description

The VALUE COLLECTION -42704-2 is a fully threaded hex socket cap screw designed for precision fastening in mechanical assemblies, tooling, and equipment maintenance applications. Built to M3 x 0.50 thread specifications with a 6 mm length under head, this screw is manufactured from alloy steel at material grade 12.9, making it one of the highest-strength classifications available in metric fasteners. A black oxide coating provides moderate corrosion resistance and a clean, uniform appearance. The hex socket drive requires an appropriate metric hex key or Allen driver for installation and removal. This item is packaged in quantities of 50, suited for shop stock or project-level use by machinists, millwrights, and maintenance technicians.

This screw is appropriate for use in compact mechanical assemblies where high clamping force is required in a small fastener footprint. The M3 x 0.50 thread pitch and 6 mm grip length make it well suited for securing small components in machinery, fixtures, jigs, and electronic enclosures. It conforms to DIN 912 and ISO 898-1 fastener standards, ensuring dimensional compatibility with metric hardware across industrial and commercial equipment platforms.

Key Features

• M3 x 0.50 metric thread with 6 mm length under head for compact fastening applications
• Alloy steel construction at material grade 12.9 for high tensile and proof load strength
• Fully threaded shank provides maximum thread engagement along the full fastener length
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Hex socket drive compatible with standard metric hex keys and Allen drivers
• Conforms to DIN 912 and ISO 898-1 standards for dimensional and mechanical consistency

Compatibility

Designed as an OEM-style replacement or shop-stock metric fastener compatible with any application requiring a DIN 912 M3 x 0.50 hex socket cap screw at grade 12.9.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a properly sized metric hex key or torx-style driver rated for the fastener grade. Always ensure the receiving thread is clean and free of debris before driving. Do not exceed the rated tightening torque for grade 12.9 M3 fasteners as specified by applicable engineering standards. Power down and de-energize any equipment before fastener service where electrical or mechanical hazard is present.
