Metric Blue UST179369 Socket Cap Screw M12 X 1.75

Product Description

The METRIC BLUE UST179369 is a partially threaded socket cap screw designed for high-strength bolted connections in precision mechanical and industrial assemblies. It features an M12 x 1.75 thread size with an 80 mm length under head, a socket cap head driven by a hex socket, and is manufactured from alloy steel to material grade 12.9. The 12.9 grade rating indicates a minimum tensile strength of 1220 MPa, making this fastener appropriate for demanding clamping applications where standard hardware is insufficient. The Metric Blue finish provides a uniform surface treatment. Licensed trade professionals, maintenance machinists, and industrial equipment technicians typically specify this fastener.

This screw is suited for mechanical, structural, and equipment assembly applications requiring a compact, high-torque hex socket drive. Partially threaded construction supports proper clamping load across an unthreaded shank. It is commonly installed in machinery frames, tooling fixtures, hydraulic components, and other assemblies built to metric dimensional standards. The fastener conforms to DIN 912 and ISO 4762 standards, making it interchangeable within those specifications across equipment designed to those fastener standards.

Key Features

• M12 x 1.75 thread size with 80 mm length under head for deep clamping reach
• Partially threaded shank for accurate clamping load distribution
• Alloy steel construction at material grade 12.9 for high tensile strength
• Hex socket drive for high-torque installation in confined spaces
• Metric Blue finish for surface identification and corrosion resistance
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a DIN 912 and ISO 4762 compliant metric socket cap screw for use in assemblies requiring M12 x 1.75 thread engagement with 80 mm length under head and grade 12.9 alloy steel construction.

Installation Notes

Installation is performed by machinists, millwrights, and mechanical technicians using a calibrated hex key or socket driver sized for the M12 cap head. Verify thread engagement depth and mating material compatibility before installation. Apply appropriate thread lubricant or threadlocker per the assembly specification. De-energize and lock out all equipment before fastener removal or installation on live machinery.
