Countersunk machine screws have a flat head with a tapered bottom, allowing the screw to rest flush with the surface of the material to which it is fastened, making them excellent for situations where the head is not visible. This keeps the skin and clothes from snagging.

Usually threaded down the shaft and may be tightened with a screwdriver or equivalent equipment. It is simple to install and remove, providing a tidy and visually pleasing finish while remaining useful. They are long-lasting, corrosion-resistant, and lightweight. Used in applications such as handrails, furniture and lighting fixtures.

How to install a captive screw and washer assembly;
1) Place the captive screw into the panel hole.
2) Thread the washer on to the screw, beyond the threaded part of the screw, which retains the screw in the panel.
