1/4" Head Self-Piercing & Self-Threading Super Saber Hex Screws, #8 x 1/2"

Manufacturer: Duro Dyne
Product Description

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.
