Washer Head Machine Screws

A washer head machine screw combines the machine screw and washer into a single component - the head is formed with an integral wide, flat flange that bears directly on the material surface, eliminating the need for a separate washer and providing a larger, cleaner bearing area than a standard pan or hex head. At the DIY Hardware Store, our washer head zinc-plated machine screws are available for the sheet metal, plastic enclosure, and light fabrication applications where an integral wide bearing face is the preferred specification.

The wide flanged head of a washer head screw resists pull-through in thin sheet materials more effectively than a standard pan head without a separate washer, and provides a cleaner, lower-profile installation than a pan head with a loose washer underneath. This makes them the preferred fastener for fixing cover plates, mounting brackets, and access panels in applications where the flange head sits directly and cleanly on the material surface.
