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.

Steel Vibration-Damping Hex Head Screws for Sheet Metal
These steel screws are zinc plated to resist corrosion in wet environments. A rubber washer cushions the screw to resist loosening from vibration. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the washer.

Sealing Blunt Screws for Sheet Metal
A rubber O-ring under the head creates a seal that withstands liquid and gas pressure. They're chemical-resistant 18-8 stainless steel and may be mildly magnetic. Often referred to as Type B thread-forming screws, they require a drilled hole and are typically used in 0.050"-0.200" material. Length is measured from under the head.

Screws for Joining Sheet Metal to Wood
Able to penetrate overlapping sheets, these screws have a secure hold in wood. The hex head allows for a firm grip with a wrench, while a rubber washer provides a watertight seal. They're corrosion-resistant-coated steel to resist corrosion in wet environments and minimize reactions between dissimilar metals. Length is measured from under the washer.

Steel Drilling Screws with Washer for Metal
These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments.
Corrosion-resistant-coated steel screws are more corrosion resistant than zinc-plated screws.

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.
