Metric Blue UST176222 Socket Cap Screw M5 X 0.8 20mm

Product Description

The METRIC BLUE UST176222 is a socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and precision equipment. Sized at M5 x 0.8 with a 20 mm length under head, this screw is fully threaded and features a hex socket drive for torque transmission with a standard hex key or Allen driver. Manufactured from alloy steel to material grade 12.9, it delivers tensile strength suited for demanding industrial and OEM applications. The metric blue finish provides a distinctive appearance and surface protection. This fastener conforms to DIN 912 and ISO 4762 standards.

This socket cap screw is used in a wide range of applications including machine building, fixture fabrication, hydraulic component assembly, and general mechanical fastening where a low-profile cap head and high clamp load are required. The M5 thread size and 20 mm under-head length make it a common choice for mounting brackets, motor components, and precision assemblies. It is typically installed by machinists, millwrights, mechanical contractors, and field service technicians working with metric-dimensioned equipment.

Key Features

• M5 x 0.8 thread size with 20 mm length under head for precise fitment
• Fully threaded body maximizes thread engagement across the full shank length
• Alloy steel construction at grade 12.9 for high tensile and proof load strength
• Hex socket drive accepts standard metric hex keys for reliable torque application
• Metric blue finish for surface identification and corrosion resistance
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a standard metric socket cap screw per DIN 912 and ISO 4762, suitable for use in any M5 x 0.8 threaded hole requiring a grade 12.9 alloy steel fastener with a hex socket cap head.

Installation Notes

Installation is performed by machinists, millwrights, or qualified mechanical technicians. Ensure the mating threaded hole is clean, properly tapped to M5 x 0.8, and free of debris before installation. Use a correctly sized metric hex key or bit to avoid rounding the socket drive. Always de-energize and lock out any equipment before accessing fastener locations in powered systems.
