Metric Blue UST176290 Socket Cap Screw M12x1.75 110mm

Product Description

The METRIC BLUE UST176290 is a metric socket cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel to material grade 12.9, this fastener delivers exceptional tensile strength for demanding clamping loads. It features a hex socket (Allen) drive and a partially threaded shank with an M12 x 1.75 thread pitch and a 110 mm length under head. The Metric Blue finish provides a controlled surface coating that aids in corrosion resistance and part identification. Licensed mechanics, millwrights, and industrial maintenance technicians are the primary installers of this class of fastener.

This socket cap screw is suited for medium-to-heavy-duty mechanical assemblies where space constraints require a low-profile cap head and an internal hex drive. Partially threaded shanks like this one are preferred in applications requiring precise shear load transfer or where the unthreaded portion must pass through a clearance hole before engaging a tapped bore. Typical applications include machine frames, fixture plates, gearbox housings, and precision equipment assemblies conforming to DIN 912 and ISO 4762 standards.

Key Features

• Alloy steel construction to material grade 12.9 for high tensile and proof load capacity
• M12 x 1.75 thread pitch per DIN 912 and ISO 4762 standards
• Partially threaded shank for accurate shear load management through clearance holes
• Hex socket drive for high-torque installation in confined spaces
• Metric Blue finish for surface protection and visual identification
• 110 mm length under head suits deep-reach fastening requirements

Compatibility

Designed as a DIN 912 and ISO 4762 compliant metric socket cap screw suitable for any tapped M12 x 1.75 bore application requiring a grade 12.9 alloy steel fastener with a partially threaded shank.

Installation Notes

Installation should be performed by a qualified millwright, machinist, or mechanical technician using a calibrated torque wrench with the appropriate hex key or Allen socket sized for M12 cap screws. Verify the receiving bore is properly tapped to M12 x 1.75 and free of debris before installation. Apply thread lubricant or thread-locking compound only when specified by the equipment manufacturer, as grade 12.9 torque values assume specific friction coefficients. Never substitute a lower-grade fastener in a joint designed for grade 12.9 hardware.
