Metric Blue UST187464 Flat Socket Cap Screw M5x0.8

Product Description

The METRIC BLUE UST187464 is a flat socket cap screw engineered to DIN 7991 standards, designed for applications where a flush or countersunk fastener profile is required. Manufactured from 12.9 grade alloy steel with a Metric Blue finish, this screw delivers high tensile strength and corrosion resistance suited to demanding mechanical assemblies. The 90-degree flat head seats flush with the mating surface, driven by a 3.00 mm hex socket. The M5x0.8 thread is fully threaded over a 30.00 mm overall length. Maintenance technicians, machinists, and mechanical contractors install this fastener in precision equipment, machine frames, and structural assemblies where a low-profile head is required.

This flat socket cap screw is appropriate for metric fastening applications across industrial, mechanical, and OEM assembly work. The 12.9 alloy steel construction makes it suitable for high-load, high-stress connections in both static and dynamic assemblies. Its Metric Blue finish provides a surface coating appropriate for controlled-environment applications. The fully threaded body ensures maximum thread engagement across the entire grip length, which is particularly useful in thin-material or through-bolt installations common in mechanical and HVAC equipment mounting.

Key Features

• 12.9 grade alloy steel construction for high tensile strength in demanding fastener applications
• 90-degree flat head profile for flush, countersunk seating in mating surfaces
• 3.00 mm hex socket drive for precise torque application with standard hex keys
• Fully threaded M5x0.8 body over 30.00 mm overall length for maximum thread engagement
• Metric Blue finish applied over alloy steel base material
• Conforms to DIN 7991 fastener standard for consistent dimensional accuracy

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M5x0.8 threaded applications in industrial machinery, equipment frames, and mechanical assemblies requiring a countersunk fastener profile.

Installation Notes

Installation is performed by machinists, mechanical contractors, or qualified maintenance technicians using a 3.00 mm hex key or hex socket driver. Always verify the mating thread condition and countersink geometry before installation. Apply appropriate torque consistent with 12.9 grade M5 fastener specifications per the equipment manufacturer or relevant fastener standards. Never reuse fasteners that show signs of thread damage, galling, or deformation.
