#1 Square Rockler Centerline 1-1/2'' Driver Bits, 3-Pack

These driver bits lock in perfectly with our matching Centerline square drive screws, resulting in positive torque applied directly to the rotation of the screw. With no energy lost to cam-out, your work will go faster and be more satisfying. And with almost no stripped screw heads, it will be easier to maintain later. Of course, the driver bits also work beautifully with any other brand of screw with the compatible drive type. Durable steel alloy for maximum durability. 1/4'' hex drive shank fits standard bit holders.
