Metric Blue UST176225 Socket Cap Screw M5x0.8 45mm

Product Description

The METRIC BLUE UST176225 is a partially threaded socket cap screw designed for high-strength fastening applications in industrial, mechanical, and manufacturing environments. It features an M5x0.8 thread size with a 45 mm length under head and is driven by a hex socket tool. Manufactured from alloy steel at a material grade of 12.9, this screw delivers exceptional tensile strength and is finished in Metric Blue for corrosion resistance and visual identification. It conforms to DIN 912 and ISO 4762 fastener standards. Machinists, millwrights, and mechanical assembly technicians are the typical installers for this fastener type.

This socket cap screw is suited for close-tolerance mechanical assemblies, machine frames, fixtures, jigs, and equipment where a recessed hex drive and high clamping force are required. The partially threaded shank allows for precise load distribution in bolted joints. Applications span general industrial machinery, hydraulic equipment, tooling assemblies, and precision mechanical components where grade 12.9 strength is specified. It is sold in minimum order quantities of 100 pieces per order.

Key Features

• M5x0.8 thread size with 45 mm length under head for deep fastening reach
• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Partially threaded shank for controlled clamping and shear load performance
• Hex socket drive for use with standard hex keys and socket drivers
• Metric Blue finish for corrosion resistance and part identification
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for mechanical assemblies requiring an M5x0.8 partially threaded socket cap screw to DIN 912 or ISO 4762 specification.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a calibrated hex key or socket driver matched to the M5 drive size. Always de-energize and lock out equipment before fastener service on live machinery. Apply thread engagement depth per the applicable engineering specification for the joint; do not rely on feel alone for grade 12.9 fasteners. Follow applicable industry standards for torque procedures when specified by the equipment manufacturer.
