Metric Blue UST176250 Socket Cap Screw M8 X 1.25

Product Description

The METRIC BLUE UST176250 is a fully threaded socket cap screw designed for high-strength fastening applications in metal fabrication, machinery assembly, and precision mechanical work. Built to DIN 912 standards from grade 12.9 alloy steel with a Metric Blue finish, this screw delivers exceptional tensile strength and corrosion resistance for demanding service environments. The hex socket drive allows for high-torque installation in tight or recessed spaces where a standard wrench cannot reach. It features an M8 x 1.25 thread size with a 12 mm length under head, making it well-suited for compact fastening configurations.

This socket cap screw is used across a wide range of industrial and mechanical applications, including equipment assembly, fixture building, and structural fastening where a flush or recessed cap head is required. The grade 12.9 material grade places it among the highest-strength fastener classifications available, making it appropriate for load-bearing joints and precision assemblies. The fully threaded shank provides maximum thread engagement across the full fastened length.

Key Features

• DIN 912 standard, grade 12.9 alloy steel for maximum tensile strength
• Fully threaded shank for complete thread engagement
• Hex socket drive allows high-torque installation in confined spaces
• M8 x 1.25 thread size, 12 mm length under head
• Metric Blue finish for corrosion resistance and part identification
• Socket cap head profile for recessed or flush mounting applications

Compatibility

Designed as a DIN 912 metric socket cap screw for use in any application requiring an M8 x 1.25 threaded fastener with a hex socket drive and socket cap head profile.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical assembly technicians using a calibrated hex key or Allen socket of the appropriate metric size. Always ensure mating threads are clean and free of debris before installation. Do not mix metric and inch-standard fasteners in the same assembly. Follow applicable torque specifications from the equipment manufacturer or relevant engineering standards for grade 12.9 fasteners.
