About this deal

The main takeaway from this is that when you are using a long extension, be sure to attach a digital torque adapter at the end for optimal tightening work. But if you are using one or two extension bars and you have a well-calibrated torque wrench, you have nothing to worry about. How Do Torque Extension Bars Work? Original Length of Torque Wrench is the length of the torque wrench without any extensions, measured in the same units (inches or centimeters). Torque (T) is the desired torque value that needs to be applied to the fastener, typically measured in pound-feet (lb-ft) or Newton-meters (Nm). A Torque Wrench Extension Calculator is a tool designed to help users determine the required extension length for a torque wrench when applying a specific torque value to a fastener. This is particularly useful in situations where a standard torque wrench’s length may not be sufficient to reach the fastener. The formula for calculating the necessary extension length is as follows:

In some cases, people have found inconsistencies with extensions. But there is a catch. All the inconsistencies around the extension are not straightforward. For example, we can talk about a universal torque wrench extension that has swivel motion at the base. Extension Length (L) is the additional length needed for the torque wrench to reach the fastener effectively, typically measured in inches or centimeters. This is a common misconception in DIY communities. The short answer is, extension doesn’t increase any torque output. But if you are too careless when using an extension bar with a torque wrench, it could reduce the overall torque output. In another instance, the torque value changes if you place an extension bar at the end of the handle instead of the drive. Torque wrenches have calibration to read the exact force you would exert from the specific length of the handlebar. Anything longer than the handlebar itself will require less force to reach the set torque value. In short, as long as you are using a straight extension for your torque wrench, the torque value stays roughly the same. On the other hand, if your torque wrench has an angle, curve, or any kind of swivel to it, the actual torque will be different. So, when you tighten a nut or bolt, it won’t be as accurate as it would be without the extension. How Much Does The Torque Value Change If You Use An Extension?What about a straight extension bar? In our experiment we found that the straight bar doesn’t really show that much deviation. It stays mostly accurate unless there is a significant amount of slag on the extension bar. But that wasn’t the case with the 30-inch to 40-inch extension bar. The results were pretty inconsistent, but not more than 2.0 points on the digital torque adapter. We also tried to hold the extension bar as straight as possible to reduce slag. That slightly improved the reading, but far from the ideal threshold. In another experiment with crow’s foot extension, the torque value stays the same as long as it is at 90 degrees with the torque wrench. If you keep it straight with the wrench bar, the increased length will give slightly greater torque value. This happens due to increased leverage. If the extension you’re about to install isn’t trusted by Enhanced Safe Browsing, it says “This extension is not trusted by Enhanced Safe Browsing.” In other cases, the extension arm that has some sort of angle and curve also shows a slightly low score on torque reading. Depending on the situation you could see 1.0 – 2.0 points of deviation from the actual torque settings.

Well, this is a very real scenario that could affect the torque value of the wrench. And interpreting the situation incorrectly will force you to deal with severe consequences. The efficiency of a torque wrench with an extension is a common matter of concern among DIY enthusiasts. This is also very important because you need extensions to reach intricate places for tightening work. And each of these extensions has a distinct purpose. Alternatively, if you want to reach a certain torque but your wrench doesn’t support those settings, here is how you can do that. Let’s say you have a 10-inch extension and your desired fastener torque is beyond your actual torque wrench capacity. Do this equation and find the torque settings that you need to increase torque with the extension. On Windows, Mac, or Linux computers, run an antivirus or anti-malware software. Remove any software programs that may be affecting Chrome. You can use any universal joint with a torque wrench as you see fit. But if you are looking to tighten any nuts or bolts to a specific torque setting, you might want to add a digital adapter at the end of the universal joint. Without the digital adapter, your fastening won’t be as accurate as the torque wrench itself. The swivel on the join will mess up the reading as it reduces the force by a couple of points. As long as you don’t need the accurate torque setting, you are good to go. Can You Use A Crow’s Foot On A Torque Wrench?

If you repaired an extension but it's still corrupted, a suspicious program might be changing this extension's files.
