Metric Blue UST176288 Socket Cap Screw M12x1.75 90mm

Product Description

The METRIC BLUE UST176288 is a partially threaded socket cap screw engineered for high-strength bolted assemblies. It features an M12 x 1.75 thread profile and a 90 mm length under head, with a hex socket drive and a low-profile socket cap head. Manufactured from alloy steel to material grade 12.9, this fastener delivers exceptional tensile and proof-load performance. The Metric Blue finish provides a uniform appearance and light corrosion resistance. It meets DIN 912 and ISO 4762 standards, making it a recognized choice for precision mechanical and structural applications.

This screw is suited for medium-to-heavy-duty bolted connections in machinery, equipment frames, tooling fixtures, and fabricated assemblies. The partial threading allows the unthreaded shank to bear shear loads cleanly, which is typical in close-tolerance through-bolt applications. Licensed mechanics, millwrights, and industrial maintenance technicians commonly install fasteners of this type. The 12.9 grade rating makes it appropriate where high clamping force is required in compact joint designs.

Key Features

• M12 x 1.75 thread size for broad metric hardware compatibility
• 90 mm length under head, partially threaded for shear-load applications
• Alloy steel construction, material grade 12.9 for maximum tensile strength
• Hex socket drive for high-torque installation in confined spaces
• Metric Blue finish applied over alloy steel for identification and light surface protection
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a DIN 912 and ISO 4762 compliant replacement or new-installation socket cap screw for any metric M12 x 1.75 threaded application requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation requires a hex socket driver or Allen key sized to the M12 cap head. De-energize and lock out any equipment before fastener service. Apply thread-locking compound or specified torque values per the equipment manufacturer's service documentation, as this prompt does not supply torque specs. Grade 12.9 fasteners must not be substituted with lower-grade hardware without engineering review.
