When Robertson Square screws are the fastener of choice on the job site, this 6" double-ended impact bit has you covered for both sizes in a single tool. Impact-rated to withstand the high-torque demands of impact drivers, the shallow tip design keeps the bit firmly seated in quick-change chucks — no slipping, no stopping to retrieve a bit that's worked its way out. With a #1 Square on one end and a #2 Square on the other, electricians and contractors can move between screw sizes without ever reaching for a second bit.
