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.

These square-drive screws have a flange under the head that distributes holding pressure and reduce the risk of crushing thin metal.

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

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

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

A rubber O-ring under the head creates a seal that withstands liquid and gas pressure.

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

These steel screws have corrosion-resistant finishes.

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

Cutting their own pilot hole and threads as you fasten them into material, these metric screws have a drilling tip.

Made from 18-8 stainless steel, these screws have good chemical resistance.

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

These steel screws have a head encapsulated by 18-8 stainless steel.

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.

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

These metric screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

18-8 stainless steel screws have good chemical resistance.

18-8 stainless steel screws have good chemical resistance.

These steel screws are hot-dipped galvanized to resist corrosion in wet environments.

With a low-profile rounded head that’s flanged to sit flush for a finished appearance, these screws press threads into wood on cabinets, trim, molding, and light duty framing.
