Metric Blue UST187472 Flat Socket Cap Screw M8x1.25

Product Description

The METRIC BLUE UST187472 is a flat socket cap screw designed for high-strength fastening applications where a flush or countersunk profile is required. Manufactured from 12.9 grade alloy steel, this screw delivers exceptional tensile and shear strength for demanding mechanical assemblies. It features an M8x1.25 thread size, a 5.00 mm hex socket drive, and a 90-degree flat head conforming to DIN 7991. The Metric Blue finish provides surface protection. At 25.00 mm overall length and fully threaded along its shank, this fastener suits precision installations where full thread engagement is critical. Typically installed by millwrights, machine technicians, and maintenance mechanics.

This flat socket cap screw is suited for use in industrial machinery, mechanical assemblies, and structural fixtures that require a low-profile, countersunk fastening solution. The 90-degree flat head seats flush with or below the mating surface, making it appropriate for applications where protruding fastener heads are not acceptable. It is fully threaded over its 25.00 mm length, providing maximum thread engagement in tapped holes or with a nut.

Key Features

• 12.9 grade alloy steel construction for high tensile strength
• M8x1.25 metric thread size, fully threaded over 25.00 mm overall length
• 90-degree flat head profile per DIN 7991 for flush or countersunk seating
• 5.00 mm hex socket drive for secure torque application
• Metric Blue finish for surface protection and identification
• Metric thread standard with DIN 7991 fastener compliance

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in tapped M8x1.25 holes in industrial, mechanical, and structural assemblies requiring a countersunk head profile.

Installation Notes

Installation requires a 5.00 mm hex socket or Allen key. Power down and de-energize any machinery before accessing fastener locations in live equipment. Apply appropriate torque per the assembly specification for 12.9 grade M8 fasteners. Do not substitute a lower-grade fastener in applications specifying 12.9 material grade.
