Introduce

Machine screws, also sometimes referred to as machine bolts, are normally smaller than the average screw. Round and Pan heads will protrude from a flat surface, while flat head machine screws are designed for holes that are countersunk so that they lay flush with the surface.

The stainless steel machine screw has a flat surface and a button head with a star driver. Colleague stainless steel has corrosion resistance and may be magnetic. The star-shaped driver has a six-point notch with a center pin, which requires a special driver to tighten or loosen the screw, so it can prevent tampering.
