These durable run down adapters (RDA) are designed to provide consistent and reliable torque readings for use with power driven torque control tools. The RDA’s reduce the impact and irregular peaks that cause poor repeatability. Each RDA has an effective torque range and will supply repeatable torque data within that range if used correctly. The run down adapter is mounted in-line between the tool drive and transducer. Mountz offers a variety of RDA styles.
