3/8" Socket Set Z-Series
The ratchet set from the Z series of Ko-ken contains 21 pieces. The soft foam insert protects the tools from damage and facilitates storage.
To the 72-tooth ratchet:
The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10°/click. The new 72 tooth ratchets move 5° click.
