Sealey Ak5513 Impact Extension Bar Set 4Pc 1/2Sq Drive

Product Information

Remember we said that it was the sag, or the angle created due to the sag, to be more specific, which was a key reason behind the torque loss? To further confirm that, a wobble extension was used under the same setting. Instead of talking in terms of theory, I’d like to summarize the results of an extensive test on this matter, which will answer the question in a more solid manner. So to settle things, yes, you can use an extension with a torque wrench without losing on torque and keeping the purpose intact as long as you can keep it perpendicular (or as close as possible) to the body of the wrench. Adjusting for The Extension Our little equation: Torque Setting = (Wrench Length × Desired Torque) ÷ (Wrench Length + Extension Length) But things got interesting when the wobble came into play. The results were fairly inconsistent when trying out different angles, as summed up below:

Halfords Advanced hand tools come with a Lifetime Guarantee. Should a Halfords Advanced hand tool fail while being used for the purpose and in the manner for which it was designed, it will be inspected and replaced. When you just measure the length of the wrench and the extension, the equation becomes much easier to comprehend.

It was time for a 38-inch extension and it averaged out at 35.1 ft-lb, which actually is a 0.86% increase in torque from the baseline. Just to give you another heads up before wrapping it up, you need to ensure that you put your hand in the right place on the wrench—at the center of the handle. Neither at the upper end nor the bottom end. In simpler terms, an extension that’ll increase the effective length of the wrench will need to be adjusted for. An increased effective length will provide more leverage than default and thus will apply a different amount of pressure than intended, killing the sole purpose of a torque wrench. At this point, no dedicated brace was used even though there was a little sag (spoiler: that’s a key reason behind the torque loss). Now that things were to be stretched further, to minimize the substantial amount of sag, a chair was used as a brace to get as accurate results as possible.

Finally, testing out with an 88-inch extension, the results came out as 9.29% torque loss without the brace and 5.72% loss with the brace. The numbers were not exactly the ones that were expected because the torque loss was rather a little less than the 64-inch extension, but the pattern was somewhat upheld, we could say. The Halfords Advanced 1/2" Drive Impact Extension Bar Set includes 50 and 150mm lengths. The extension bars have been manufactured from tough chrome molybdenum steel for added strength and durability.You have a wrench with a length of 24 inches and you have to put an extension of 4 inches on it to reach where you intend to. The recommended torque setting for the fastener is 180 lbs. What torque setting do you set the wrench on for a smooth sail? You just need to know the actual length of the wrench and the extension. That’s it. That’s the apparently obscure part, I suppose. Halfords Advanced modular trays are designed to help you build your own ideal tool kit. Choose the tools that you need for the job and then choose the storage that you need. Our Halfords Advanced modular tray storage case will hold up to three trays for a portable tool kit, or build the complete tool storage solution using Halfords tool chests and cabinets.
