Duro Dyne® Self-Piercing Point Screw, SDU Series, 1/2 in Overall Length, Socket Head, #8 Drive, Zinc Chromate
These self piercing screws are 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 the metal rapidly and almost without effort. All ZD "Super Saber" Point Screws have a 1/4" hex head. ZD Screws over 3/4" require a pre-drilled hole.
