Tri-Wing® Rounded Head Screws for Sheet Metal
These screws require a Tri-Wing® driver for installation and removal. Made from 18-8 stainless steel, they are chemical resistant and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.
Phillips Bits
Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.
