RS PRO Pozidriv Countersunk Stainless Steel Machine Screw, M2.5 Thread, 12mm Length, DIN 965, A2 Grade, 179-5677

The RS PRO Pozidriv Countersunk Stainless Steel Machine Screw, model 179-5677, is designed for technical fastening in demanding environments where corrosion resistance and precise assembly are essential. Manufactured from robust A2-304 stainless steel, this machine screw delivers exceptional durability and long service life, making it suitable for a variety of industrial, mechanical, and electronic assemblies.

This model features a countersunk head, which sits flush with the surface once installed, providing a smooth finish ideal for applications where aesthetics and safety are important. The Pozidriv drive ensures a secure and reliable torque transfer, minimizing cam-out and allowing consistent installation and removal with compatible tools.

With a metric thread size of M2.5 and a length of 12mm, this screw matches widely used standard hardware requirements and fits precisely in pre-tapped holes or with nuts of matching specification. The DIN 965 compliance guarantees adherence to rigorous international standards for dimensions, threading, and performance, giving confidence to engineers and installers in both new builds and repairs.

Typically, these screws are employed in machinery, automotive components, electrical control panels, manufacturing assemblies, instrumentation, and other applications where stainless fasteners are required to resist oxidation, damp, or chemical exposure. The A2 material grade provides a balance of mechanical strength and corrosion protection, suitable for both indoor and sheltered outdoor use.

Installation is straightforward using Pozidriv screwdrivers or automated fastening tools, and the countersunk design ensures the head does not protrude above the mounting surface.
