Metric Blue UST183997 Flat Socket Cap Screw M3x0.5

Product Description

The METRIC BLUE UST183997 is a flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. Built to DIN 7991 standards, it features a 90-degree flat head driven by a 2.00 mm hex socket. The screw is manufactured from 10.9 grade alloy steel, indicating a high-strength fastener with a tensile strength class suited for demanding mechanical assemblies. It carries a Metric Blue finish for corrosion resistance and identification. The M3x0.5 thread is fully threaded along its 10.00 mm overall length. Machinists, millwrights, and mechanical contractors use this fastener where a low-profile head seating flush with or below a surface is required.

This fastener is appropriate for precision mechanical assemblies, machinery, fixtures, and industrial equipment where metric hardware is specified. The M3x0.5 thread size and 10.00 mm length make it a common choice for light structural connections, panel mounting, and component fastening in tight clearance areas. Its fully threaded design ensures maximum thread engagement across the entire shank length, which is particularly useful in thin-material or close-tolerance applications.

Key Features

• 90-degree flat head seats flush or countersunk for a low-profile installation
• 2.00 mm hex socket drive compatible with standard metric hex keys and bit sets
• 10.9 grade alloy steel construction for high tensile and proof load strength
• Fully threaded along the entire 10.00 mm overall length for maximum thread engagement
• Metric Blue finish provides corrosion resistance and visual metric identification
• Manufactured to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M3x0.5 threaded bores in machinery, fixtures, and industrial assemblies requiring a countersunk hex socket fastener.

Installation Notes

Installation requires a 2.00 mm hex key or socket bit; use a calibrated torque tool appropriate for 10.9 grade M3 fasteners per the governing mechanical or equipment specification. Ensure the mating bore is drilled and countersunk to the correct 90-degree angle to achieve proper head seating. Inspect threads for contamination before installation. Follow applicable machinery or equipment manufacturer guidelines for fastener replacement and torque procedures.
