PLAIN FLAT HEAD SOCKET SCREW BSW

Plain finish flat head (countersunk) socket screws with British Standard Whitworth (BSW) threads are typically manufactured from high-grade alloy steel. These fasteners feature a flat top that tapers into a cone shape, allowing them to sit flush with the material surface in countersunk holes.

Standards: Often manufactured to BS2470 or ASTM F835 specifications.
Material & Finish: Usually made of alloy steel with a plain finish (bare metal), which may have a light oil coating for basic corrosion resistance.
Applications: Designed for moderate fastening tasks like machine guards, hinges, and covers where a flush appearance is needed. They are generally not recommended for critical high-strength applications where standard socket head cap screws are better suited.
Drive Type: These screws utilize an internal hex (Allen) drive, requiring a hex key or Allen wrench for installation.
