These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance.

These screws have the strength of 410 stainless steel with added corrosion resistance.

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.

Beveled under the head for use in countersunk holes.

Made from stainless steel to resist galvanic corrosion, use these screws to fasten aluminum to aluminum and steel framing. They save you time and effort by drilling their own holes and fastening in a single operation.

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

18-8 stainless steel screws have good chemical resistance.

Stronger and more wear resistant than 18-8 and 316 stainless steel, these screws are mildly chemical resistant.

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

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

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

Made from 18-8 stainless steel, these screws are chemical resistant.

18-8 stainless steel screws have good chemical resistance.

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

Install and remove these screws with a tamper-resistant spanner driver.

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

Also known as pin-in-hex, install and remove these screws with a tamper-resistant hex driver.

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

A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess.

Stronger and more wear resistant than 316 and 18-8 stainless steel, these screws are mildly chemical resistant.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

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

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

For a finished appearance that reduces the chance of snags on other material, these screws fit snugly in countersunk holes and have a domed head.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

A wide cutting slot provides excellent chip clearing and low driving torque in soft metal.

Also known as Swageform screws, threads at the tip are designed to grab material for a fast start with low torque in a wide range of materials.

Ribs under the head act as a brake to prevent over-tightening and damaging threads.

Alternating high and low threads minimize driving torque and allow the screw to hold more material between threads for a stronger hold and better strip-resistance than standard drywall screws for wood.

A drill point powers through metal up to 0.105" thick.

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.

These screws have a head that's one-third smaller than other drywall screws. Use them to attach drywall to metal studs up to 0.036" thick.

A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess.

These screws speed installation by drilling, tapping, and fastening wood and metal in a single operation.
