RQH22DX24 Female Ratchet Head, 22D, 24mm

Tohnichi RQH22DX24 is a precision female ratchet head designed as an interchangeable accessory for torque wrenches, enabling smooth, one-way tightening of external hex nuts and bolts in restricted access areas across automotive assembly, electronics manufacturing, and precision engineering tasks. Featuring a compact 22D (22 mm diameter round end) for seamless integration and a 24 mm female ratchet mechanism for direct socket engagement, this head delivers reliable torque transfer without slippage, compatible with select Tohnichi CL, CSP, BCSP, and other series wrenches equipped with 22D interfaces. Ergonomically lightweight with robust construction, it supports rapid head exchanges to optimize workflow efficiency, minimize downtime, and ensure consistent torque application in space-constrained operations.
