Overtime, all power tools start to drift out of tolerance. When testing a power tool using a torque tester or reaction style torque sensor, always use a quality joint rate simulator otherwise known as a run down adapter (RDA).
The purpose of using a RDA is to simulate the fastening process of a screw. These durable run down adapters by Mountz are designed to provide consistent and reliable torque readings for use with power driven torque control tools. The RDA reduces the impact and irregular peaks that cause poor repeatability. Making a safer world through accuracy and precision is the core purpose at Mountz.
The run down adapter is mounted in-line between the tool’s drive and the torque tester or sensor, which may require other adapters or attachments. The RDA is designed to operate in a clockwise direction only. Apply torque until RDA is run down and the tool shuts-off. Then note or save the readings with the torque analyzer. After each run down, the RDA should be backed off just enough to fully release the tension. It’s important not to back out completely or the adapter will unscrew and could be damaged on the next rundown by cross-threading.
Using a quality run down adapter during the torque testing process makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners.
