Features

The Koken 3725ZS Ratchet Handle is the newest iteration of Koken’s Z-Series, combining what people already loved about these ratchets with entirely new strengths. In the past the Z-Series has been known for its very low backlash, small head sizes, and high torque ranges. The new 72 tooth ratchet is designed without compromising on the traditional strengths of the Z-Series. The 72 tooth ratchet moves 5°/click and utilizes a single spring. Expertly crafted 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 and has a 10% higher torque upper limit compared to legacy products.
