18-8 stainless steel screws have good chemical resistance.

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

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

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

With more points of contact than Phillips-, slotted-, and square-drive screws, you can firmly press these Torx-drive screws into wood without stripping them or damaging the recess—their threads create a tight hold.

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

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

18-8 stainless steel screws have good chemical resistance.

These 316 stainless steel screws have excellent resistance to chemicals and salt water.

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

Screws are beveled under the head for use in countersunk holes.

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

Thread-forming screws press threads into drilled holes for a tight, vibration-resistant assembly.

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.
