No pre-drilling is required with the Type 17 self-drilling tip, which also saves time on the jobsite, minimizes splitting, while the sharp threads and a “U” clearing thread reduce friction along the shank.
The result? Lower driving torque and extended battery life for your tools. The wide flat head features nibs and under-head cutting serrations, ensuring smooth, clean countersinks and flush finishes every time. The T-40 Star Drive provides a firm grip that keeps the screw securely attached to the bit, even when working overhead or in tight spaces.
