SP Tools patented Gear Drive spanners are designed for maximum torque and reliability, with 72 teeth that only need 5° of space per turn. Easily change rotation direction by flipping the spanner.
SP box ring end spanners have a deeper flat drive ring, making them ideal for loosening hard-to-reach, worn fasteners by increasing contact area with the nut or bolt head for greater torque.
Made of Chrome Vanadium Steel (Cr-V) for strength and durability
