For professionals who need a custom torque solution, the Wera 7790/1 weld-on insert tool offers a blank canvas to create specialized attachments. Unlike standard fixed inserts, this tool is designed to be welded onto your own fabricated component, allowing you to build a torque wrench adapter perfectly suited to your unique application. Its 9x12 mm square drive fits directly into compatible torque wrenches, and the high-performance steel construction with chrome plating ensures durability and corrosion resistance. This is the ideal choice for custom tool fabrication, prototyping, or repairing specialized equipment where off-the-shelf inserts simply won't do.

In daily use

In a workshop or production environment, this insert tool becomes the foundation for a tailored torque solution. Weld it to a specialized socket, a custom open-end head, or any other attachment you require, then insert the 9x12 mm square drive into your torque wrench.
