Metric Blue UST184146 Flat Socket Cap Screw M16x2 30mm

Product Description

The METRIC BLUE UST184146 is a flat socket cap screw engineered for high-strength metric fastening applications. It features a 90-degree flat head with a 10 mm hex socket drive and is manufactured from 12.9 grade alloy steel, the highest common strength grade in the metric fastener system. The M16x2 thread profile is fully threaded over its 30 mm overall length. The metric blue finish provides a degree of corrosion resistance and serves as a visual identifier for metric hardware. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies where a flush or countersunk head profile is required.

This screw is suited for applications where the fastener head must sit flush with or below the surface of the mating component. Typical uses include machine frames, structural brackets, hydraulic component mounting, and industrial equipment assemblies. The fully threaded 30 mm length maximizes thread engagement in tapped holes. The DIN 7991 fastener standard governs the dimensional and performance requirements for this screw, making it directly interchangeable with other DIN 7991 compliant hardware of the same size and grade.

Key Features

• 12.9 alloy steel construction delivers high tensile and proof load capacity
• 90-degree flat head profile allows flush or countersunk installation
• 10 mm hex socket drive for use with standard Allen or hex key tooling
• Fully threaded M16x2 shank maximizes thread engagement in tapped bores
• Metric blue finish for visual metric identification and light surface protection
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a DIN 7991 compliant flat socket cap screw in M16x2 thread size, compatible with any tapped M16x2 metric hole requiring a 90-degree countersunk flat head fastener.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener torque requirements for 12.9 grade hardware. Ensure the mating component is countersunk to the correct 90-degree angle before installation. De-energize and lock out all equipment before performing fastener work on machinery. Do not substitute lower-grade fasteners in applications where 12.9 grade is specified.
