Metric Blue UST179773 Socket Cap Screw M8x1.25 10mm

Product Description

The METRIC BLUE UST179773 is a metric socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and industrial equipment. It features an M8 x 1.25 thread profile with a 10 mm length under head and is fully threaded along its entire shank. The socket cap head accepts a hex socket drive for high-torque installation in confined spaces. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suitable for demanding structural and mechanical applications. The Metric Blue finish provides a corrosion-resistant coating that meets DIN 912 fastener standards.

This screw is suited for use in industrial machinery, precision equipment, hydraulic components, and mechanical sub-assemblies where a compact, high-strength fastener is required. The M8 thread size and short 10 mm under-head length make it appropriate for applications with limited material thickness or close-tolerance bore depths. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly install this type of fastener. It is sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• M8 x 1.25 thread size with 10 mm length under head for compact fastening
• Fully threaded shank provides maximum thread engagement throughout the grip length
• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Hex socket drive allows high-torque installation in restricted access areas
• Metric Blue finish offers corrosion resistance on the alloy steel base
• Conforms to DIN 912 fastener standard for dimensional accuracy and interchangeability

Compatibility

Designed as an OEM-style replacement or service fastener for metric-threaded assemblies requiring a DIN 912 socket cap screw in M8 x 1.25 thread size with a 10 mm under-head length.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a calibrated hex key or socket driver sized for the M8 cap head. De-energize, depressurize, or otherwise safe off any equipment before removing or replacing fasteners in load-bearing or pressurized assemblies. Use a torque wrench where joint specifications require controlled clamp load. Inspect mating threads for damage or contamination before installation to ensure proper seating.
