Metric Blue UST176303 Socket Cap Screw M16 X 2 70mm

Product Description

The METRIC BLUE UST176303 is a partially threaded socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel at material grade 12.9, it delivers exceptional tensile strength for demanding bolted joints. The M16 x 2 thread and 70 mm length under head make it suitable for medium-to-large fastening tasks where precise clamping force and fatigue resistance are required. The hex socket drive allows torque application with a standard Allen key or hex bit driver. The Metric Blue finish provides a degree of surface protection. This fastener is typically installed by machinists, millwrights, maintenance technicians, and mechanical assemblers.

This screw is suited for use in general industrial machinery, hydraulic equipment, tooling fixtures, structural steel connections, and heavy equipment assembly. The partially threaded shank provides a clean bearing surface in clearance holes, helping maintain accurate joint alignment. Applications span both OEM manufacturing environments and field maintenance settings where metric fasteners are specified to DIN 912 or ISO 4762 standards.

Compatibility

Designed as an OEM-style metric fastener replacement or new installation screw for machinery and assemblies requiring DIN 912 or ISO 4762 compliant M16 x 2 socket cap screws.

Installation Notes

Installation is typically performed by licensed millwrights, machinists, or qualified maintenance technicians. Always de-energize and lock out equipment before servicing fastened assemblies. Use a calibrated torque wrench and the appropriate hex key or socket bit sized for M16 socket cap screws. Follow applicable industry torque specifications for grade 12.9 fasteners as defined by the relevant equipment manufacturer or engineering standard.
