STURTEVANT RICHMONT We build tools that are meant to last. When you have torque testers in the field that last for more than forty (40) years and are still accurate, reliable, and durable, there is no need to replace them. We have torque screwdrivers that are more than 40 years old and they still come back for calibration. We feel bad when an old tool comes back and we can't repair it because the parts aren't being made anymore. If we had the parts, we'd fix the tool.
