Brass screws are corrosion resistant in wet environments and electrically conductive.

These steel screws are zinc plated to resist corrosion in wet environments.

A flange under the head distributes holding pressure and reduces the risk of crushing thin metal.

A thick, decorative head provides a finished appearance.

More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water.

The S-shaped drive can be installed with a standard slotted driver, but requires a special tool for removal.

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.

With a square-drive head, these screws attach drywall to metal studs up to 0.036" thick. The head is one-third smaller than other drywall screws.

These square-drive screws have a drill point that powers through drywall and into metal studs up to 0.105" thick. Heads are one-third smaller than those of other drywall screws.

Made from brass, these screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water.

Nylon screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

One-third the weight of steel, aluminum screws resist corrosion in wet environments.

Create a decorative appearance on your finished product—the head of these screws is painted.

Stainless steel screws have excellent corrosion resistance in most environments.

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.
