Value Collection -42704-1 M3 X 0.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42704-1 is a fully threaded hex socket cap screw sized M3 x 0.50 with a 5 mm length under head. Manufactured from alloy steel to material grade 12.9, this fastener delivers high tensile strength suited to precision clamping applications in machinery, fixtures, and equipment assemblies. A black oxide finish provides mild corrosion resistance and a uniform dark appearance. The hex socket drive accepts a standard hex key for installation in confined spaces where a wrench or external drive cannot reach. This screw conforms to DIN 912 and ISO 898-1 fastener standards.

This screw is appropriate for mechanical assemblies, jigs, tooling, and light industrial equipment where a compact, high-strength fastener is required. The M3 x 0.50 thread is a standard metric coarse pitch used across a wide range of precision components. The fully threaded shank allows engagement along the entire usable length, making it suitable for thin workpieces and short-engagement tapped holes. Installation is performed by machinists, millwrights, and maintenance technicians using standard metric hex keys.

Key Features

• M3 x 0.50 metric coarse thread, fully threaded shank
• 5 mm length under head for short-engagement applications
• Alloy steel construction, material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Hex socket drive allows installation in tight or recessed locations
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for tapped M3 x 0.50 holes in metal, plastic, and composite assemblies across general industrial and mechanical applications.

Installation Notes

Install using a correctly sized metric hex key to avoid rounding the socket drive. Verify that the tapped hole thread pitch matches M3 x 0.50 before installation. Apply appropriate thread-locking compound or preload torque per the assembly specification. Grade 12.9 fasteners should not be welded, as the heat treatment affects tensile properties.
