The Mountz 070844 RDA-S0 Run Down Adapter (1.5mm Hex x 1/4” M/Sq. Dr.) is specialized devices designed to simulate “soft joint” conditions during the testing and calibration of power-driven torque control tools. Engineered for use with the Mountz EZ-TorQ torque analyzers, these adapters help deliver consistent, reliable torque readings by minimizing the irregular peaks and impact loads that can compromise test accuracy and repeatability.

Mounted in-line between the power tool drive and the torque transducer, the RDA provides controlled joint simulation, significantly improving test consistency for high-speed, power-driven tools. This setup allows technicians to more accurately measure tool performance under real-world conditions, enhancing test validity and reducing calibration errors.

Each RDA model has a defined effective torque range and, when used correctly, delivers highly repeatable torque data. The compact design minimizes the space between the power tool and analyzer, promoting ease of use and precise alignment, which leads to improved test results. Designed to operate in a clockwise direction only, the Mountz 070844 RDA-S0 Run Down Adapter (1.5mm Hex x 1/4” M/Sq. Dr.) must be completely backed up after each run down to maintain accuracy.

Ideal for tool calibration labs, assembly lines, and quality control departments, the Mountz 070844 RDA-S0 Run Down Adapter (1.5mm Hex x 1/4” M/Sq. Dr.) is essential for companies seeking to meet ISO 9001, IATF 16949, and other quality standards. It provides a dependable method for accurately simulating joint conditions and ensuring that torque tools perform within specified parameters. Whether you’re verifying pneumatic, electric, or battery-powered tools, the RDA helps technicians achieve accurate, repeatable results with every test.
