Features and Benefits:
- Z-Series 3/8″ Sq.Dr. Flexible Ratchet, Reversible (L=280mm), 72 Tooth
3/8″ Square drive, Z-Series, Longer 280mm Length, Flex Head, 72 Tooth Ratchet. The patented design of the 72T incorporates dual pawls. Ko-ken has ensured that their hallmark low backlash and small size are preserved. Through extensive testing over four years, they have achieved a delicate balance of low spring pressure to maintain the low-torque backlash characteristic of Ko-ken tools. Additionally, the finer 72 teeth design provides increased surface area contact with the gear, resulting in a 10% higher torque upper limit.
