Truss head Phillips Self Tapping Screws for Sheet Metal
Also known as extra-wide rounded head self tapping screws. This screw for use with thin steel plates features a head with a large outer diameter, and can be fastened just with a pilot hole—no tap or nut required.
18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They have a wider head than standard rounded head screws to distribute holding pressure and reduce the risk of crushing thin metal.
