WIHA 43634 T-handle adapter
The WIHA 43634 is an insulated T-handle adapter for 1/4" sockets, designed for use with the TorqueVario®-S T electric torque screwdriver. It enables more controlled and stable work with sockets when torque tightening is required in professional electrical work.
The key here is not just the design, but the safety surrounding it. The adapter is individually tested according to IEC 60900 and approved for safe work on live parts up to 1,000 V AC. This means it belongs where insulated tools and documented safety features are required.
The specified torque range is 0–20 Nm, and the total length is 88 mm. With a weight of 35 g, it is compact to use, and its small dimensions make it easy to integrate into the rest of the tool kit. For technicians and electricians, it is an especially practical spare part or accessory when using sockets with proper torque control.
