#6 X 3/8 Hex Washer Tek Screw / Zinc Plated

Tek screws, also called self-drilling screws, are self-tapping fasteners that have a drill bit end allowing them to be used for screwing materials such as wood and metal together without pre-drilling. Tek screws are best fitted with a high-speed impact drive. These feature a hex washer head. (HWTS638D)
