Installing or replacing the deck on your utility trailer or car hauler, or mounting a tool box, winch or other accessory?

Just pre-drill a 7/32 pilot hole and secure the screw with a T30 star bit. The screws are black oxide-coated for corrosion resistance and manufactured from quality steel for durability.
