of a washer. The head shape also gives a larger contact area with the surface, which means a snag free

for sheet metal projects and applications where there is minimal clearance, such as sliding supports
in draws and cabinets. Imperial Unified Coarse thread version. Phillips drive is x-shaped for installation
with a Phillips screw driver.
