Metric Blue UST176302 Socket Cap Screw M16x2 75mm

Product Description

The METRIC BLUE UST176302 is a metric socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features an M16 x 2 thread size with a 75 mm length under head and is partially threaded along the shank. The cap head accepts a hex socket drive for installation with a standard Allen or hex key. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suited for critical clamping applications. The Metric Blue finish provides surface identification consistent with the 12.9 grade standard. This fastener conforms to ASME B18.3.1M.

This screw is used in machine assembly, equipment manufacturing, tooling fixtures, and structural bolted connections where high-clamp-load capacity is required. The partially threaded shank provides a shoulder bearing surface, making it appropriate for applications where the unthreaded portion must pass through a clearance hole before engaging a threaded bore. Installers in industrial maintenance, precision machining, and mechanical construction trades regularly specify 12.9 grade socket cap screws for these use cases.

Key Features

• M16 x 2 thread size with 75 mm length under head
• Partially threaded shank for clearance-hole applications
• 12.9 material grade alloy steel for high tensile and proof load ratings
• Hex socket drive compatible with standard Allen keys and socket drivers
• Metric Blue finish for grade identification per metric fastener convention
• Conforms to ASME B18.3.1M dimensional standard

Compatibility

Designed as a standard metric replacement or new-install socket cap screw for M16 x 2 threaded bores in industrial machinery, structural assemblies, and mechanical equipment requiring ASME B18.3.1M-compliant 12.9 grade fasteners.

Installation Notes

Installation is typically performed by millwrights, machinists, or mechanical assemblers using a properly sized hex key or socket driver. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for 12.9 grade M16 fasteners. Ensure the mating threaded hole is clean and free of debris before installation. Do not substitute a lower-grade fastener in applications specified for 12.9 material.
