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

18-8 stainless steel screws have good chemical resistance.

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

18-8 stainless steel screws have good chemical resistance.

Because these steel screws cut threads into drilled holes as they’re turned, they require less driving torque and cause less stress on material than thread-forming screws. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting boards.

Threads change direction to cut into composites and push material back into the hole to prevent distorting the surface around the hole.
