Metric Blue UST176305 Socket Cap Screw M16 X 2 90mm

Product Description

The METRIC BLUE UST176305 is a partially threaded socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and manufacturing applications. It features an M16 x 2 thread size with a 90 mm length under head, a socket cap head, and a hex socket drive. Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile strength for critical fastening joints. The metric blue finish provides corrosion resistance and a standardized identification color consistent with DIN 912 and ISO 4762 specifications. Licensed trades and machine technicians install this fastener in precision assemblies requiring controlled preload and reliable clamping force.

This screw is suited for heavy-duty industrial equipment, hydraulic systems, tooling fixtures, and structural mechanical assemblies where high clamp load and precise fit are required. Its partial threading is appropriate for applications requiring a shoulder or grip length beneath the head. The hex socket drive accommodates standard hex key sets and torque wrenches commonly used in machine shops, maintenance shops, and field mechanical service environments.

Key Features

• M16 x 2 thread size with 90 mm length under head for deep fastening applications
• Partially threaded shank for controlled grip length and shoulder-style fitment
• Alloy steel construction at material grade 12.9 for maximum tensile strength
• Hex socket drive for use with standard hex keys and torque wrenches
• Metric blue finish for corrosion resistance and metric-standard visual identification
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for industrial equipment, machinery, and mechanical assemblies requiring an M16 x 2 partially threaded socket cap screw conforming to DIN 912 and ISO 4762 standards.

Installation Notes

Installation should be performed by qualified mechanical technicians or tradespeople familiar with high-strength metric fastener procedures. De-energize and lock out all power sources before servicing any equipment that requires fastener replacement. Use a calibrated torque wrench to achieve the manufacturer-specified clamp load for grade 12.9 fasteners - consult the equipment service manual for the required torque value. Do not substitute a lower-grade fastener in any application that specifies grade 12.9.
