Metric Blue UST179707 Socket Cap Screw M5 X 0.8 40 Mm

Product Description

The METRIC BLUE UST179707 is a metric socket cap screw designed for precision fastening in industrial, mechanical, and manufacturing applications. It features an M5 x 0.8 thread size with a 40 mm length under head and is partially threaded for controlled engagement depth. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suitable for demanding clamped joint applications. The hex socket drive accepts a standard Allen key or hex bit. The Metric Blue finish provides a uniform appearance and mild corrosion resistance. This screw conforms to DIN 912 and ISO 4762 fastener standards.

This socket cap screw is used in machine assembly, equipment maintenance, and precision mechanical builds where a low-profile, high-strength fastener is required. The M5 thread size and 40 mm under-head length make it appropriate for moderate-depth threaded holes in steel, aluminum, and similar substrates. It is sold individually but requires a minimum order quantity of 100 pieces per order. Machinists, millwrights, maintenance technicians, and mechanical assemblers are the typical installers.

Key Features

• M5 x 0.8 thread size with 40 mm length under head for accurate fitment in metric-threaded assemblies
• Grade 12.9 alloy steel construction for high clamping force and tensile strength
• Partially threaded shank provides controlled thread engagement depth
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Conforms to DIN 912 and ISO 4762 fastener standards for dimensional consistency
• Metric Blue finish for identification and mild surface protection

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric socket cap screw suitable for M5 x 0.8 threaded holes in industrial machinery, mechanical assemblies, and equipment maintenance applications.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a calibrated hex key or Allen driver matched to the socket head size. Always verify thread pitch and hole depth before installation to avoid cross-threading or bottoming out. Apply thread-locking compound or anti-seize as required by the assembly specification. De-energize and isolate any machinery before servicing fasteners on moving or powered components.
