RH15DX24 Ring Head, 15D, 24mm

Tohnichi RH15DX24 is a precision ring head designed as an interchangeable accessory for torque wrenches, enabling accurate tightening of external hex nuts and bolts in restricted access areas across automotive assembly, electronics manufacturing, and precision engineering tasks. Featuring a compact 15D (15 mm diameter round end) for seamless integration and a 24 mm ring opening for direct fastener engagement, this head delivers reliable torque transfer without slippage, compatible with select Tohnichi CTA, CTB, CL, PCL, and YCL series wrenches equipped with 15D 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.
