Value Collection 42704 M3 X 0.50 Hex Socket Cap Screw 50 Pack

Product Description

The VALUE COLLECTION 42704 is a fully threaded hex socket cap screw in M3 x 0.50 metric thread, with a 4 mm length under the head. Manufactured from alloy steel with a black oxide finish, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suited for demanding mechanical assemblies. The hex drive socket accepts a standard hex key for installation in tight spaces where a conventional wrench cannot reach. Each order ships in a pack of 50 pieces, making it practical for production, maintenance, and repair applications.

This screw is used in precision mechanical assemblies, machine components, tooling fixtures, and general industrial applications where a compact, high-strength fastener is required. The M3 thread size and 4 mm under-head length make it appropriate for light-gauge brackets, electronic enclosures, small engine components, and similar assemblies where space and fastener profile are critical. The black oxide coating provides a degree of corrosion resistance and reduces light reflection in optical or instrumentation assemblies.

Key Features

• M3 x 0.50 metric thread, fully threaded shank
• 4 mm length under head for compact, low-profile installations
• Alloy steel construction, material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Hex socket drive for installation in confined spaces with a hex key
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Packed in quantities of 50 pieces per order

Compatibility

Designed as a standard DIN 912 hex socket cap screw suitable for any M3 x 0.50 threaded application requiring a 12.9 grade alloy steel fastener with black oxide finish.

Installation Notes

Installation is typically performed by a mechanic, millwright, or assembler using a properly sized metric hex key. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not exceed the torque capacity appropriate for a 12.9 grade M3 fastener, and never use an oversized driver that could damage the hex socket. Follow applicable equipment manufacturer specifications and relevant industry standards for fastener torque and thread engagement depth.
