Bosch's concrete screw and anchoring system is the perfect fit for your concrete and masonry needs! Electricians, plumbers and remodelers are using these systems every day when fastening screws into brick, concrete and block. After using the system, including the TC2005 Concrete Screw Drill Bits, at trade shows and in field testing, users are excited to add this product to their repertoire. They were even more excited when they learned it was going to be available by Bosch. Bosch is the first name pros think of when purchasing a hammer drill or carbide, so it is a natural fit.
