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

Product Information

At this point, a pattern had been found that as the extension length kept increasing, the torque loss was higher (without the brace). To see if the pattern was valid or not, things were stretched out even further. But things got interesting when the wobble came into play. The results were fairly inconsistent when trying out different angles, as summed up below: All these attempts were made from completely different angles, intentionally. The inconsistency of the outcome validates the hypothesis. What Causes Torque Loss?

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. 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.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? In the first attempt, the extension was kept straight and it averaged out at 33.7 ft-lb as an average of 3 results as always, which is the same as the ½-inch drive impact extension that was first used. 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.

But here’s the upfront conclusion if you’re a skimmer—the extension does not cause torque loss as long as it’s perfectly perpendicular to the body of the wrench. But achieving the perfect angle is often tougher than it’s thought to be. 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. 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. 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.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. 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. Next up, two extensions were put together making a combined length of 19-inch, and that averaged out at 33.5 ft-lb, representing a torque loss of 3.83% compared to the baseline. 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. Features & Benefits: Some wrenches will have a marking on the handle for reference, and that’s the point to measure up to from the center of the drive. If the marking isn’t there, take the middle point of the handle as your reference.
