The METRIC BLUE UST179702 is a metric socket cap screw designed for precision fastening applications where high strength and tight tolerances are required. Threaded M4 x 0.7 with a 10 mm length under head, it is fully threaded along its entire shank and driven with a hex socket. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suitable for demanding mechanical assemblies. The metric blue finish provides corrosion resistance and easy identification in mixed-fastener environments. This screw is installed by machinists, millwrights, maintenance technicians, and equipment assemblers working on precision machinery and industrial equipment.
This screw suits residential and commercial mechanical assemblies requiring a compact, high-strength metric fastener. The M4 x 0.7 thread size and 10 mm under-head length make it a practical fit for tight-clearance applications in equipment housings, brackets, and machine components. It conforms to DIN 912 and ISO 4762 standards, making it interchangeable with other fasteners specified to those standards. Sold individually with a minimum order quantity of 100 pieces per order.
Designed as a DIN 912 and ISO 4762 compliant metric socket cap screw suitable for M4 x 0.7 threaded applications in mechanical assemblies, equipment housings, and machine components requiring a grade 12.9 alloy steel fastener.
Installation is performed by machinists, maintenance technicians, or equipment assemblers using a calibrated hex key or Allen driver of the appropriate metric size. Always verify the mating thread specification before installation to avoid cross-threading or stripping. Power down and de-energize any equipment before accessing fastened assemblies. Follow the equipment manufacturer torque specifications for M4 grade 12.9 fasteners as outlined in the relevant assembly documentation.
