Metric Blue UST187468 Flat Socket Cap Screw M6x1 12.9

Product Description

The METRIC BLUE UST187468 is a flat socket cap screw engineered to DIN 7991 standards for precision fastening in metal fabrication, machinery, and structural assemblies. It features an M6x1 thread size with a 30.00 mm overall length and is fully threaded from tip to head. The 90-degree flat head profile allows the fastener to sit flush or countersunk within the mating surface, eliminating protrusions that could interfere with moving parts or mating components. Driven by a 4.00 mm hex socket, it is compatible with standard Allen key sets and hex bit drivers. The 12.9 alloy steel grade delivers high tensile strength suited for high-load applications.

This screw is used in metric mechanical assemblies where a low-profile flush-mount fastener is required. Common applications include machine tool construction, automotive component assemblies, jigs and fixtures, and precision equipment where surface clearance is critical. The Metric Blue finish provides a uniform appearance and mild corrosion resistance. It is installed by machinists, millwrights, and mechanical assemblers working to metric design specifications.

Key Features

• DIN 7991 standard - ensures dimensional consistency with metric engineering specifications
• 90-degree flat head with 4.00 mm hex socket drive for flush countersunk installation
• M6x1 thread size, 30.00 mm overall length, fully threaded for maximum thread engagement
• 12.9 alloy steel material grade for high tensile and proof load strength
• Metric Blue finish for uniform appearance and mild surface protection
• Metric thread standard for compatibility with ISO metric fastener systems

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for metric mechanical assemblies requiring a DIN 7991 flat socket cap screw in M6x1 thread size.

Installation Notes

Installation should be performed by qualified mechanical assemblers or machinists familiar with metric fastener torque specifications for 12.9-grade hardware. Use a calibrated hex socket driver sized at 4.00 mm to avoid rounding the drive recess. Always ensure the countersink angle in the mating component matches the 90-degree head angle before seating the fastener. Follow applicable equipment manufacturer torque tables for M6 12.9 fasteners - do not use torque values from other material grades.
