SH27DX46 Open End Head, 27D, 46mm

Tohnichi SH27DX46 is a precision open end head designed as an interchangeable accessory for torque wrenches, facilitating accurate tightening of external hex nuts and bolts in restricted access areas across automotive assembly, electronics manufacturing, and precision engineering tasks. Featuring a compact 27D (27 mm diameter round end) for seamless integration and a 46 mm open end for direct fastener engagement, this head delivers reliable torque transfer without slippage, compatible with select Tohnichi CL, CSP, BCSP, and other series wrenches equipped with 27D 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.
