Metric Blue UST187462 Flat Socket Cap Screw M5x0.8

Product Description

The METRIC BLUE UST187462 is a flat socket cap screw designed for applications requiring a low-profile, flush or countersunk fastener. Built to DIN 7991 standards, it features an M5x0.8 thread and is manufactured from grade 12.9 alloy steel, delivering high tensile strength in a compact form. The 3.00 mm hex socket drive accepts a standard hex key for installation and removal. The Metric Blue finish provides a consistent surface treatment suited to general industrial and mechanical assemblies. This screw is fully threaded over its 20.00 mm overall length and carries a 90-degree flat head profile. Machinists, maintenance technicians, and assembly professionals working with metric hardware specify this fastener where head clearance is limited.

This flat socket cap screw fits residential and commercial mechanical assemblies, machine frames, fixtures, and equipment enclosures where a countersunk fastener is required. The M5 thread size and 20.00 mm length suit medium-duty clamping applications across a wide range of metal and engineered-plastic substrates. It is commonly used in precision machine assembly, industrial equipment maintenance, and fabrication work where the fastener head must sit flush with or below the mating surface.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load performance
• DIN 7991 fastener standard ensures dimensional consistency and interchangeability
• 90-degree flat head profile allows flush or countersunk installation
• 3.00 mm hex socket drive compatible with standard metric hex keys
• Fully threaded 20.00 mm overall length maximizes thread engagement
• Metric Blue finish applied over alloy steel for uniform surface appearance

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for M5x0.8 metric threaded applications conforming to DIN 7991 specifications.

Installation Notes

Installation is performed with a 3.00 mm hex key or hex socket driver. Verify that the mating part has a properly machined 90-degree countersink to match the flat head geometry before driving the fastener. Grade 12.9 fasteners are susceptible to hydrogen embrittlement if exposed to certain plating processes or improper handling; follow manufacturer and industry guidelines for storage and reuse. Always ensure the mating thread is clean and free of debris before assembly.
