Value Collection KP82185 Flat Socket Cap Screw M3x0.5 25 Pack

Product Description

The VALUE COLLECTION KP82185 is a metric flat socket cap screw designed for flush or countersunk fastening applications requiring high tensile strength and a clean finished appearance. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers reliable clamping force in tight assemblies where a low-profile head is required. The M3x0.5 thread size and 8.00 mm overall length make it well suited for precision mechanical assemblies. The 2.00 mm hex socket drive requires a properly sized hex key for installation. Sold in a pack of 25, these screws are appropriate for machinists, maintenance technicians, and fabricators working on metric-standard equipment.

This screw is used in applications where a standard socket head cap screw would protrude above the mating surface. The 90 degree flat head profile sits flush when installed in a properly chamfered or countersunk hole. Typical applications include machine tool assemblies, jig and fixture construction, electronic enclosures, and industrial equipment panels. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or precision instrument applications. The fully threaded shank engages the entire length of the tapped hole, maximizing thread engagement in thin or shallow bosses.

Key Features

• 12.9 grade alloy steel construction for high tensile strength in demanding fastening applications
• 90 degree flat head profile for flush countersunk installation
• 2.00 mm hex socket drive for precise torque application with standard hex keys
• Fully threaded shank maximizes thread engagement throughout the fastened length
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Conforms to DIN 7991 fastener standard for metric dimensional consistency

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw compatible with M3x0.5 threaded holes in metric-standard assemblies and components.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a 2.00 mm hex key or driver bit sized to the socket. Verify the mating hole is properly countersunk to the correct 90 degree angle before installation to ensure full head seating. Do not overtighten, as 12.9 grade fasteners are susceptible to hydrogen embrittlement failure if subjected to improper torque procedures. Always confirm thread engagement depth is sufficient for the applied load before final assembly.
