Metric Blue UST179471 Socket Cap Screw M20 X 2.5 70mm

Product Description

The METRIC BLUE UST179471 is an M20 x 2.5 socket cap screw designed for high-strength fastening in demanding mechanical and structural applications. It features a socket cap head driven by a hex socket, allowing high torque application in tight clearances. Manufactured from alloy steel to material grade 12.9, it carries a Metric Blue finish for identification and corrosion resistance. The screw is fully threaded with a 70 mm length under head and conforms to DIN 912 and ISO 4762 standards. Licensed trades and maintenance professionals rely on this fastener where rated load capacity and dimensional precision are critical.

This socket cap screw is suited for industrial machinery, heavy equipment, die and mold assemblies, and precision mechanical structures where a recessed hex drive and high clamp load are required. The M20 x 2.5 thread size and 70 mm length under head make it appropriate for medium-to-heavy flange connections, bracket mounts, and machine frame assemblies. The 12.9 grade rating indicates suitability for high-stress bolted joints in both OEM manufacturing and field maintenance contexts.

Key Features

Compatibility

Designed as a standard DIN 912 and ISO 4762 compliant M20 x 2.5 socket cap screw suitable for any application requiring a grade 12.9 hex socket fastener of this thread pitch and length.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using a calibrated hex key or socket driver sized for M20 cap screws. Always consult the equipment manufacturer torque specification table for grade 12.9 fasteners at M20 x 2.5 before tightening. Inspect threads and mating surfaces for damage or contamination before assembly. Do not substitute a lower-grade fastener in applications specified for 12.9 material.
