Fence works with stainless steel screws and an 18V impact driver Works perfectly. Used 1 tip that still looks and works like new after 25 screws. For comparison, the grade B**** is rounded down after 3-4 screws. A properly sized head allows you to "pre-install" the screws on the drive head and operate them with a one-handed tool. Admittedly, my experience was simple. This is an expected consumable, as evidenced by the presence of a large package.
