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. Their thin head also means they won't stick out of decking, trim, and other finished surfaces. With a corrosion-resistant coating, these screws resist up to 1,500 hours of salt spray. They're green, so they blend in with most treated wood.

Length is measured from the top of the head.
