SH19DX18 Open End Head, 19D, 18mm

Tohnichi SH19DX18 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 19D (19 mm diameter round end) for seamless integration and an 18 mm open end for direct fastener engagement, this head delivers reliable torque transfer without slippage, compatible with select Tohnichi CTA, CTB, CL, YCL, PCL, CSP, CF, CEM, and CDB series wrenches equipped with 19D 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.
