Metric Blue UST194854 Flat Socket Cap Screw M5x0.8

Product Description

The METRIC BLUE UST194854 is a flat socket cap screw engineered to DIN 7991 specifications in metric sizing. It features an M5x0.8 thread and an overall length of 8.00 mm, making it suited for flush or countersunk fastening applications where a low-profile head is required. The screw is manufactured from 12.9 grade alloy steel, which is among the highest strength classifications for metric fasteners, delivering excellent tensile and shear resistance. A Metric Blue finish provides corrosion resistance and visual identification for metric hardware. The 3.00 mm hex socket drive accepts a standard hex key for installation and removal. This part is sold individually but requires a minimum order quantity of 100 units.

This flat socket cap screw is used in mechanical assemblies, precision equipment, and structural applications where a 90-degree countersunk head must sit flush with or below the surface of the mated material. It is fully threaded along its entire length, allowing full thread engagement across a range of material thicknesses. It is commonly installed by machinists, maintenance technicians, and industrial assemblers working with metric hardware in machinery, fixtures, and fabricated components.

Key Features

• DIN 7991 standard - ensures dimensional interchangeability with other compliant metric fasteners
• 12.9 alloy steel construction - high tensile strength suitable for demanding mechanical applications
• 90-degree flat head profile - designed for flush countersunk installations
• 3.00 mm hex socket drive - compatible with standard metric hex keys and Allen drivers
• Fully threaded - maximizes thread engagement over the full 8.00 mm length
• Metric Blue finish - corrosion-inhibiting coating with metric-standard color identification

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in any application requiring an M5x0.8 fully threaded countersunk fastener with a 3.00 mm hex socket drive.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a calibrated torque wrench or hex key sized to the 3.00 mm socket drive. Countersink the mating material to match the 90-degree head angle before driving the fastener. De-energize and de-pressurize any equipment before replacing fasteners on live machinery. Do not exceed the rated torque for 12.9 grade M5 fasteners, and consult the equipment manufacturer specifications for final torque values.
