When you’re fastening indoor sheet metal, you need fast, reliable screws that cut their own path and sit flush to finish the job neatly. The Grip-Rite Pro-Twist No. 12 screws deliver exactly that—self-drilling, self-tapping, and ready to tackle metal-to-metal or lightweight metal-to-assembly tasks without pre-drilling.
These screws are crafted from durable steel and finished in zinc plating for dependable indoor performance. The flat head is precisely countersunk to sit flush, while a Phillips drive provides steady control and reduces cam-out, even in tight spaces. With a 2-1/2 in length and a No. 12 size, they strike the right balance between grip and surface coverage for common sheet metal applications.
