Metric Blue UST194855 Flat Socket Cap Screw M5x0.8

Product Description

The METRIC BLUE UST194855 is a flat socket cap screw engineered to DIN 7991 standards, designed for applications requiring a low-profile, countersunk fastener with high tensile strength. Built from 12.9 grade alloy steel with a Metric Blue finish, this screw delivers the clamping force and corrosion resistance that precision mechanical assemblies demand. The M5x0.8 thread pitch and 40.00 mm overall length make it a go-to choice for close-tolerance work. Drive engagement is through a 3.00 mm hex socket, and the fastener is fully threaded along its entire length. Installation professionals in manufacturing, mechanical maintenance, and equipment fabrication will find this fastener suited for tight clearance environments where a standard hex head will not fit.

This flat socket cap screw is used in metric-threaded assemblies across industrial machinery, hydraulic components, structural fixtures, and precision equipment enclosures. The 90-degree flat head seats flush with or below the workpiece surface, eliminating protrusion in moving assemblies or panels. It is commonly specified in OEM manufacturing, field repair, and equipment overhaul work where DIN 7991 compliance is required and high clamping loads are present. This item is sold individually but carries a minimum order quantity of 10 units.

Key Features

• DIN 7991 standard flat socket cap screw for metric applications
• 12.9 grade alloy steel construction for high tensile and shear strength
• 90-degree flat head with 3.00 mm hex socket drive for low-profile seating
• M5x0.8 thread size, fully threaded over 40.00 mm overall length
• Metric Blue finish for corrosion resistance and surface identification
• Fully threaded shank maximizes thread engagement across the full fastener length

Compatibility

Designed as an OEM-style and replacement fastener for metric-threaded assemblies requiring a DIN 7991 flat socket cap screw in M5x0.8 thread size.

Installation Notes

Installation requires a 3.00 mm hex socket driver or Allen key; use a calibrated torque wrench appropriate for 12.9 grade M5 fasteners and follow the torque specifications published by the equipment manufacturer. Ensure mating threads are clean and free of debris before driving. Do not substitute an imperial hex key, as improper driver fit can round the socket. This fastener should be installed by qualified mechanical technicians familiar with metric fastener standards.
