The ratchet section has a unique "UNIT DRIVE" structure and has a large surface area in contact with nuts and bolts, allowing it to be turned smoothly by applying force evenly and stably.
With gentle torque transmission, it can be turned without slipping even with a tapped bolt.
The handle part has a groove, making it easy to hold and hard to put on your hands.
