ATI Cone Shaped Unplated Washer - Counter Sunk 5/16in To Standard 5/16in Conversion

This ATI conversion washer is made from steel and is designed to change a countersunk 5/16 inch hole to a standard 5/16 inch hole. It's a simple but effective piece when you need to adapt a mounting surface for different hardware. The cone shape allows it to sit flush in a countersunk recess, providing a flat surface for a standard bolt head or nut.

The unplated steel construction means it's ready for whatever finish you need, whether that's paint, plating, or just left as is depending on your application. It's a well-built little part that solves a common problem when working with engine components or custom setups where hole sizes might not perfectly match your hardware.
