Value Collection A996725 Hex Socket Cap Screw M3x0.50 25pk

Product Description

The VALUE COLLECTION A996725 is a partially threaded hex socket cap screw in M3 x 0.50 metric thread, designed for precision fastening applications in mechanical assemblies, manufacturing, and maintenance work. At 40 mm length under head, this screw is produced from alloy steel to material grade 12.9, which indicates high tensile strength suitable for load-bearing joints. The black oxide finish provides a degree of corrosion resistance and reduces surface reflectivity. Sold in a pack of 25, this fastener meets DIN 912 and ISO 898-1 standards, making it appropriate for applications where dimensional and mechanical compliance is required. Mechanical assemblers, machinists, and maintenance technicians are the typical users.

This fastener is used in light machinery, fixtures, jigs, electronic enclosures, and general metalwork requiring a compact, high-strength socket-drive screw. The M3 x 0.50 thread size fits standard M3 metric tapped holes. Partial threading allows the unthreaded shank to act as a locating or shoulder feature in close-tolerance applications. The hex socket drive accepts a standard 2.5 mm hex key or Allen wrench, making it accessible in tight clearance situations common in industrial and fabrication settings.

Key Features

• M3 x 0.50 metric thread with 40 mm length under head
• Alloy steel construction at material grade 12.9 for high tensile strength
• Partially threaded shank suitable for close-tolerance and shoulder-fit applications
• Black oxide coating for mild corrosion resistance and low-reflectivity finish
• Meets DIN 912 and ISO 898-1 fastener standards
• Hex socket drive accepts a standard 2.5 mm hex key
• Pack of 25 screws per package

Compatibility

Designed for use in standard M3 x 0.50 metric tapped holes. Suitable for mechanical assemblies, fixtures, and equipment requiring DIN 912-compliant hex socket cap screws.

Installation Notes

Installation should be performed by qualified mechanical assemblers or maintenance technicians familiar with metric fastener torque requirements for grade 12.9 alloy steel. Ensure the mating tapped hole is clean and properly formed to the M3 x 0.50 thread profile before installation. Use the correct 2.5 mm hex key to avoid rounding the socket drive. Do not exceed the torque capacity of the tapped material, particularly when threading into aluminum or plastic.
