The METRIC BLUE UST187535 is a flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastener with high tensile strength. Built to DIN 7991 standards, it features an M6x1 metric thread and a 4.00 mm hex socket drive. The screw is manufactured from grade 12.9 alloy steel, which delivers high clamping force in demanding mechanical assemblies. It has a 90-degree flat head profile and is fully threaded along its 16.00 mm overall length. The Metric Blue finish provides a distinctive identification coating. This fastener is installed by machinists, millwrights, equipment technicians, and field service professionals working on precision assemblies.
This flat socket cap screw is suited for metric fastening applications in industrial machinery, tooling fixtures, automotive components, and mechanical equipment where a countersunk, flush-seating fastener is required. The fully threaded shank and fine M6x1 pitch make it appropriate for thinner material stacks and applications that demand maximum thread engagement over the full fastener length. It is sold individually with a minimum order quantity of 100 pieces.
Designed as an OEM-style replacement or standard metric fastener for equipment and assemblies requiring a DIN 7991 M6x1 flat socket cap screw in grade 12.9 alloy steel.
Installation is performed by qualified mechanical technicians using a calibrated 4.00 mm hex key or socket driver. De-energize, depressurize, or lock out the assembly before fastener replacement per applicable safety standards. Grade 12.9 fasteners should be torqued using a calibrated torque wrench to manufacturer-specified values for the joint design. Do not substitute a lower-grade fastener in applications engineered for 12.9 material grade.
