Metric Blue UST179706 Socket Cap Screw M5x0.8 30mm

Product Description

The METRIC BLUE UST179706 is a metric socket cap screw designed for precision fastening applications where high clamping force and a low-profile head are required. Manufactured from alloy steel to material grade 12.9, this screw delivers tensile strength suited for structural, mechanical, and industrial assemblies. The M5 x 0.8 thread pitch paired with a 30 mm length under head makes it well-suited for close-tolerance bolted joints. A Metric Blue finish provides corrosion resistance for the fastener surface. The hex socket drive accepts a standard hex key for reliable torque application in confined spaces where a wrench cannot be used.

This socket cap screw is used in mechanical assemblies, machine frames, tooling fixtures, and industrial equipment where a recessed-head fastener is specified. The partial threading leaves a smooth shank section near the head, which is common in applications requiring precise joint alignment or shear load distribution. Tradespeople, machinists, and maintenance technicians working to DIN 912 or ISO 4762 standards will find this screw a direct-fit replacement or new-installation fastener in metric-specified equipment. It is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Alloy steel construction with 12.9 material grade for high tensile and proof load strength
• M5 x 0.8 thread size with 30 mm length under head, partially threaded
• Hex socket drive accepts standard hex key for torquing in restricted clearances
• Metric Blue finish applied for surface protection
• Conforms to DIN 912 and ISO 4762 fastener standards
• Socket cap head profile keeps the fastener low-profile within the assembly

Compatibility

Designed as an OEM-style metric socket cap screw conforming to DIN 912 and ISO 4762 standards, suitable for use in any metric-specified mechanical assembly calling for an M5 x 0.8 partially threaded socket cap screw at grade 12.9.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized hex key or hex bit driver rated for grade 12.9 fasteners. Always de-energize or lock out equipment before servicing any fastened assembly. Do not substitute a lower-grade fastener in applications specifying 12.9 material grade, as doing so may result in joint failure under load. Follow the equipment manufacturer torque specifications for M5 fasteners when tightening this screw.
