Metric Blue UST190385 Flat Socket Cap Screw M12x1.75

Product Description

The METRIC BLUE UST190385 is a flat socket cap screw designed for high-strength metric fastening applications. It features an M12x1.75 thread size, a 90-degree flat head, and a hex socket drive sized at 8 millimeters. Built from 12.9 grade alloy steel, this screw delivers maximum tensile strength suitable for precision mechanical assemblies, industrial equipment, and structural connections where a flush or countersunk fastener profile is required. The Metric Blue finish provides corrosion resistance and visual identification as a metric-standard fastener. At 20 millimeters overall length and fully threaded, it is well suited to close-tolerance applications where thread engagement across the full shank length is critical.

This flat socket cap screw conforms to DIN 7991 and is intended for use in metric fastening applications across manufacturing, industrial machinery, and mechanical assembly environments. Typical installers include millwrights, maintenance technicians, and mechanical assemblers working on equipment where a low-profile countersunk head is needed. The 12.9 material grade makes it appropriate for high-load joints where standard hardware-grade fasteners would be insufficient. Minimum order quantity is 5 pieces.

Key Features

• 12.9 grade alloy steel construction for maximum tensile and proof load strength
• 90-degree flat head profile for flush or countersunk installations
• Hex socket drive with 8 millimeter drive size for secure torque application
• Fully threaded shank along 20 millimeter overall length
• Metric Blue finish for corrosion resistance and metric identification
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for applications requiring an M12x1.75 fully threaded countersunk fastener in 12.9 alloy steel.

Installation Notes

Install using an 8 millimeter hex socket or hex key driver rated for high-torque applications. Ensure the mating countersink angle matches the 90-degree head geometry before driving. Avoid mixing metric and unified thread hardware in the same joint. Follow applicable equipment manufacturer torque specifications when fastening 12.9 grade hardware, as overtightening can exceed joint yield limits.
