Metric Blue UST193582 Flat Socket Cap Screw M3x0.5

Product Description

The METRIC BLUE UST193582 is a flat socket cap screw designed for low-profile fastening applications where a flush or countersunk installation is required. Built to DIN 7991 standard, this screw features an M3x0.5 thread size and an overall length of 8.00 mm. It is fully threaded and driven with a 2.00 mm hex socket. Manufactured from 10.9 grade alloy steel and finished in a metric blue coating, it delivers the high tensile strength required in precision mechanical assemblies. This fastener is well suited for machinists, maintenance technicians, and assembly professionals working with metric hardware.

This flat socket cap screw is used wherever a 90-degree countersunk head profile is needed to sit flush with or below a mating surface. Typical applications include machine frames, fixtures, tooling plates, and precision equipment assemblies requiring metric fasteners at the M3 size range. The metric blue finish provides a degree of corrosion resistance suitable for general industrial environments. It is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• DIN 7991 standard for consistent dimensional and mechanical compliance
• 90-degree flat head profile for flush countersunk installations
• 2.00 mm hex socket drive for secure torque transfer in tight spaces
• 10.9 grade alloy steel construction for high tensile strength
• Fully threaded along the entire 8.00 mm length
• Metric blue finish for corrosion resistance in general industrial use

Compatibility

Designed as a metric-standard flat socket cap screw per DIN 7991, suitable for use in any application requiring an M3x0.5 fully threaded countersunk hex socket fastener.

Installation Notes

Installation should be performed by a qualified machinist or assembly technician using a calibrated 2.00 mm hex key or hex socket driver. Ensure the mating material is properly countersunk at 90 degrees before installation to allow full seating of the flat head. Do not over-torque; refer to published torque tables for 10.9 grade M3 fasteners per your applicable industry standard. Inspect threads in the mating component for cleanliness and proper thread engagement before driving the fastener.
