Duro Dyne Screws
Self piercing screws designed for light to medium gauge materials, the Super Saber Point offers one-step fastening. Its time saving performance is related to the saber-sharp piercing point with a "fine-cut" machine thread which pierces the metal upon contact. Once pierced, the thread propels the screw through metal rapidly and almost without effort.
Self drilling Pro-Point Screws, with a precision formed drill point, are designed to fasten heavy gauge metals. These screws assure accurately sized holes for maximum holding power, eliminating the need for hole preparation and frequent alignment problems encountered in parts assembly.
