Malco's Zip-in® screws are a top choice among HVAC professionals for fastening sheet metal and ductwork. The unique double-thread design and a sophisticated heat-treating process work together to deliver superior performance. The result is a screw with a fine, sharp point that offers excellent penetrating power in heavier gauge metals without sacrificing strength. This design allows for faster driving and more reliable installations compared to other self-piercing screw types.
