NEW 72T Z-Series Ratchets

1/4", 3/8" and 1/2"

The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design. The dual pawl 72 tooth design utilizes a single spring. We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken's hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit.
