Metric Blue UST176289 Socket Cap Screw M12 X 1.75

Product Description

The METRIC BLUE UST176289 is an M12 x 1.75 socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from Grade 12.9 alloy steel with a Metric Blue finish, this screw delivers exceptional tensile strength and corrosion resistance in demanding environments. The hex socket drive accepts a standard hex key for precise torque application in confined or recessed spaces. At 100 mm length under head with partial threading, it is suited for clamped-joint applications where thread engagement is controlled at the grip zone. Manufactured to DIN 912 and ISO 4762 standards, this fastener meets rigorous dimensional and mechanical tolerances expected in precision assembly work.

This socket cap screw is used in machine assembly, tooling fixtures, hydraulic equipment, and heavy fabrication where high-clamp-load fasteners are required. The M12 x 1.75 thread pitch and 100 mm body length make it a common choice for medium-to-heavy structural connections in both OEM manufacturing and maintenance repair operations. The partial threading is appropriate for through-bolt and clearance-hole configurations where the unthreaded shank bears shear loads. Installation is typically performed by machinists, millwrights, or maintenance technicians.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• M12 x 1.75 thread size with 100 mm length under head, partially threaded
• Hex socket drive for torque application in tight or countersunk locations
• Metric Blue finish for corrosion protection and identification
• Manufactured to DIN 912 and ISO 4762 dimensional standards
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or standard-stock socket cap screw for any M12 x 1.75 threaded application requiring a DIN 912 or ISO 4762 compliant fastener with a 100 mm length under head.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated torque wrench and the correct hex key size for the M12 socket cap head. De-energize all equipment and relieve hydraulic or pneumatic pressure before fastener removal or replacement in live assemblies. Grade 12.9 fasteners should not be substituted with lower-grade hardware, as clamp load requirements are grade-specific. Follow applicable industry or equipment manufacturer torque specifications, which are not provided with this part.
