QH Ratchet Head
QH ratchet heads have a small tightening radius to facilitate effective tightening in cramped areas. The square drive QH10D-1/4, QH15D-3/8 and QH22D-1/2 models are one size smaller than the regular models, so their sockets are cheaper.
◆ How to order
Specify “Tohnichi”, then “Model”.
Example: Tohnichi QH10D
Note 1: For models with a square drive 25.4mm or larger, use with a through-hole socket.
Note 2: Use QH15D-3/8 and QH22D-1/2 at no more than the permissible torque (Tmax).
Note 3: See here for square drive dimensions.
Note 2: Use QH15D-3/8 and QH22D-1/2 at no more than the permissible torque (Tmax).
Note 3: See here for square drive dimensions.
