Engineered for strength and built to perform, the Pro-Grade 8-Piece SAE Combination Wrench Set is designed for serious torque and durability. Each wrench is forged from heat treated chrome vanadium steel and finished with black phosphate coating to protect against rust, wear, and corrosion. Featuring Pro-Grade’s Dyna Drive torque system, the box ends apply force to the sides of fasteners—not the corners—helping to reduce rounding and increase power. Chamfered edges provide a smooth, secure fit, making these wrenches ideal for job site pros and home garage projects alike. Made to work, proven to last, and backed for life. Built and tested to meet or exceed ANSI (American National Standards Institute) specification B107.6.
