Metric Blue UST179708 Socket Cap Screw M5 X 0.8 50mm

Product Description

The METRIC BLUE UST179708 is an M5 x 0.8 alloy steel socket cap screw with a 50 mm length under head and a partially threaded shank. Built to material grade 12.9, this fastener delivers high tensile strength for demanding mechanical assemblies. The hex socket drive accepts a standard hex key for controlled torque application in tight clearances. It meets DIN 912 and ISO 4762 standards, making it a reliable choice for precision fastening applications in industrial, mechanical, and equipment maintenance work. Machinists, millwrights, and maintenance technicians are the primary installers.

This socket cap screw is suited for light machinery, tooling fixtures, mechanical enclosures, and equipment frames where a low-profile clamping head and high clamp load are required. The Metric Blue finish provides a degree of corrosion resistance over bare steel. Partial threading allows for greater shank rigidity and precise location in through-hole applications. It is sold individually but requires a minimum order quantity of 100 pieces, making it appropriate for production line restocking or maintenance kits.

Key Features

• Hex socket drive for use with standard hex keys or hex bit drivers
• Meets DIN 912 and ISO 4762 fastener standards
• Metric Blue finish for surface protection and part identification
• Partial threading provides shank rigidity and accurate hole location

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric socket cap screw for use in M5-threaded mechanical assemblies requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a hex key or hex bit driver sized for M5 socket cap screws. De-energize and lock out all power sources before servicing any equipment where fasteners are being replaced. Apply thread lubricant or thread-locking compound only as specified by the equipment manufacturer. Torque to the assembly manufacturer's specification for grade 12.9 M5 fasteners - do not exceed rated torque.
