A Phillips #3 bit that slips out of the screw head, walks across the surface, or strips the recess before the screw is fully driven is a time killer. This 2-inch Phillips #3 insert bit is designed for the specific recess depth and angle of #3 Phillips head screws — it seats positively and doesn't cam out under real torque. The 2-inch length gives you reach for countersunk screws in structural connections. The impact-rated design survives the repeated high-torque impacts of impact drivers without cracking. Standard in contractor tool bags across northeast Nebraska and northwest Iowa. In stock at Crofton Lumber (Crofton, NE) and Akron Lumber (Akron, IA) — ready for pickup today.
