Q: If I put an adapter on the wrench do I have to recalculate the torque?
A: It depends on what type of adapter you have. If you have a drive size adapter, such as a 1/2” to 3/4” socket adapter, then the torque value remains the same. If you are using a crowfoot adapter, which effectively lengthens the wrench, then use the adapter formula found on the torque facts page.
Q: I have 3 torque wrenches should I buy a tester so I can certify the wrench myself?
A: Generally speaking, it is not cost effective to purchase calibration equipment for a small amount of torque wrenches.
Q: How often should I calibrate my wrench?
A: CDI recommends a calibration interval of once a year or every 5000 cycles, whichever comes first.
Q: Why isn’t calibration under warranty?
A: All CDI products are calibrated before leaving the factory. CDI cannot guarantee the customers’ proper use and care of its torque equipment, therefore, we cannot warranty the calibration of any tool.
Q: Where can I purchase CDI Torque products?
A: Click on the Distributor Locator button on top and enter your 5 digit zip code to locate your nearest CDI distributor.
Q: Can I purchase tools directly from CDI?
A: Generally the answer is no. CDI does not sell directly to any end user. We sell our products exclusively through authorized distributors.
Q: Where can I get parts for my CDI Torque wrench?
A: Contact one of our distributors found on the Purchase Information page.
Q: Does CDI repair other brands or torque wrenches?
A: CDI repairs and calibrates only CDI manufactured equipment.
Q: How do I maintain and use my CDI torque wrench?
A: See Torque Facts – Safety and Proper Usage.
Q: Can I use a “cheater bar” on a torque wrench?
A: You should never, under any circumstances, use a “cheater bar” with a torque wrench. Not only is the accuracy adversely affected, but also serious bodily injury may result.
Q: Is the torque wrench accuracy affected if I use an extension?
A: It depends on what type of extension you are using. If you are using an extension that is vertical to the drive, it has no affect on the accuracy. If you are using an extension that is horizontal to the drive, such as a crowfoot, making the effective length longer, then you need to use the Adapter Torque Formula found under the Torque Facts page.
