The METRIC BLUE UST180375 is a flat socket cap screw engineered for precision metric fastening in high-strength applications. Built to DIN 7991 standard, this screw features a 90-degree flat (countersunk) head with an 8 mm hex socket drive and is fully threaded along its 25 mm overall length. The M12x1.75 thread size and 12.9 material grade alloy steel construction make it suitable for critical load-bearing assemblies where tensile strength and dimensional accuracy are required. The Metric Blue finish provides a controlled surface coating. Licensed tradespeople and MRO professionals specify this fastener where flush or countersunk mounting is needed in metal-to-metal joints.
This flat socket cap screw is used in applications requiring a low-profile, countersunk fastener profile in metallic assemblies. Typical install scenarios include machine frames, brackets, jigs, and fabricated steel components in industrial, mechanical, and equipment manufacturing environments. Its fully threaded design ensures consistent thread engagement across the full 25 mm length, which is especially useful when fastening into tapped blind holes or thin mating members. Trades including millwrights, maintenance technicians, and mechanical contractors commonly use this fastener type during equipment assembly, maintenance, and repair work.
Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M12x1.75 tapped holes in metal assemblies requiring a countersunk fastener profile.
Installation requires a calibrated torque wrench and an 8 mm hex key or hex socket bit rated for 12.9-grade fasteners. Verify that the mating tapped hole conforms to M12x1.75 metric thread specifications before installation. De-energize and lock out any equipment before performing fastener service on live machinery per applicable safety codes. Do not substitute a lower-grade fastener in applications specifying 12.9 material grade, as substitution may compromise joint integrity.
