Metric Blue UST176300 Socket Cap Screw M16x2 55mm

Product Description

The METRIC BLUE UST176300 is a metric socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and manufacturing applications. It features an M16x2 thread with a 55 mm length under head and is fully threaded along its shaft. The screw is driven by a hex socket (Allen key) and is manufactured from alloy steel to material grade 12.9, making it suitable for joints that require high clamping force and resistance to fatigue. The Metric Blue finish provides a degree of surface protection. This fastener conforms to DIN 912, the widely recognized standard for socket head cap screws.

This screw is used in applications that demand a flush or recessed fastener profile with reliable torque transfer. Typical installation scenarios include machine frames, hydraulic equipment, tooling fixtures, and structural assemblies where a cylindrical socket head is preferred over a hex bolt head. Grade 12.9 alloy steel construction makes it appropriate for high-load environments in both OEM manufacturing and field maintenance contexts. It is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working with metric fastener systems.

Key Features

• M16x2 thread size conforming to DIN 912 standard
• 55 mm length under head, fully threaded
• Alloy steel at material grade 12.9 for high clamping strength
• Hex socket drive for precise torque application in confined spaces
• Metric Blue finish for surface identification and corrosion resistance
• UNSPSC Code 31161501 for procurement classification

Compatibility

Designed as an OEM-style metric fastener for use in any application requiring a DIN 912 socket head cap screw with M16x2 thread and 55 mm length under head.

Installation Notes

Installation requires a properly sized hex socket (Allen) driver or wrench bit rated for grade 12.9 fastener torque loads. Always clean and inspect the threaded bore before installation to prevent cross-threading. Torque to the value specified by the equipment manufacturer or applicable engineering standard for grade 12.9 M16 fasteners. Do not use an undersized hex key, as this can round the socket drive and compromise the fastener.
