The ROCO™ Wood to Steel screw is specifically designed for increased holding power and an incredibly clean finish. When engaging the wood, the screw effortlessly drills through the wood while the wings mill and oversized hole. When the screw engages the steel base, the oversized hole prevents threads from engaging the wood, lifting wood and steel apart (jacking). The specially engineered drill point cuts fast through the steel and firmly clamps the wood and steel together.
