Metric Blue UST184009 Flat Socket Cap Screw M4x0.7 16mm

Product Description

The METRIC BLUE UST184009 is a flat socket cap screw engineered to DIN 7991 standards for precise, flush-mount fastening in metric applications. It features an M4x0.7 thread, a 2.50 mm hex socket drive, and a 90-degree flat head that sits flush with or below the mating surface when fully seated. Manufactured from alloy steel at material grade 10.9, this screw delivers high tensile strength suitable for demanding mechanical assemblies. The Metric Blue finish provides a light corrosion-resistant coating. The screw is fully threaded along its 16 mm overall length. Machinists, maintenance technicians, and assembly professionals working with metric hardware will find this fastener suited to tight-tolerance installations.

This flat socket cap screw is used in mechanical, industrial, and equipment assembly applications where a countersunk, flush-mount fastener is required. The 90-degree flat head profile makes it appropriate for panel mounting, machine guards, brackets, and similar installations where head protrusion must be minimized. Grade 10.9 alloy steel construction makes it suitable for high-load, vibration-prone environments common in production equipment and fabricated assemblies. This screw is sold individually but requires a minimum order of 100 pieces per order, making it appropriate for shop stock or production runs.

Key Features

• DIN 7991 standard flat socket cap screw with 90-degree countersunk head for flush mounting
• M4x0.7 metric thread, fully threaded along the 16 mm overall length
• 2.50 mm hex socket drive for standard hex key installation
• Grade 10.9 alloy steel construction for high tensile and shear strength
• Metric Blue finish for light surface protection and identification

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for M4x0.7 threaded holes requiring a 90-degree countersunk hex socket fastener in grade 10.9 alloy steel.

Installation Notes

Install with a 2.50 mm hex key or socket bit sized for standard hex drive fasteners. Ensure the mating hole is properly countersunk to 90 degrees to achieve full flush seating. De-energize or lock out any equipment before fastener replacement or removal in live machinery. Follow applicable torque specifications from a recognized fastener standard or equipment manufacturer documentation, as no torque value is supplied with this part.
