18-8 Stainless Steel Extra-Wide Rounded Head Screws for Sheet Metal
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. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

Super-Corrosion-Resistant 316 Stainless Steel
Extra-Wide Rounded Head Screws for Sheet Metal
More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water and may be mildly magnetic. They have a wider head than standard rounded head screws to distribute holding presure and reduce the risk of crushing thin metal. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.

Rounded Head Screws with Washer for Sheet Metal
A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw. They penetrate 0.025" and thinner sheet metal. Length is measured from the edge of the head. Head height includes the washer.
Black-phosphate and black-oxide steel screws are mildly corrosion resistant in dry environments.
Chrome-plated steel screws have a bright and attractive finish. They're corrosion resistant in wet environments.

Extra-Wide Rounded Head Drilling Screws for Metal
The extra-wide truss head distributes holding pressure to reduce the risk of crushing thin metal. Use these screws to secure metal wire to steel framing. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they have a zinc plating to resist corrosion in wet environments. Length is measured from under the flange. Head height includes the flange.

Drilling Screws for Joining Fabric to Metal
These screws have a free-rotating, permanently attached washer that remains stationary while tightening to prevent bunching while attaching tarps and other fabric to metal. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they're zinc-plated to resist corrosion in wet environments. Length is measured from the edge of the head.
