To endure your have your desired torque setting, the first product in the set is a 1/4-inch drive torque wrench with an accuracy rating of ±4 percent and a torque range of just 1.5 to 16.5 foot-pounds. The second is a 3/8-inch drive torque wrench, with an accuracy rating of ±4 percent and a range of 5 to 80 foot-pounds. The last wrench in the set has a 1/2-inch drive, an accuracy rating of ±4 percent, and a torque range of 20 to 150 foot-pounds, perfect for working on a motorcycle. Measure the length of the torque wrench from the square drive to the point where the weight is hanging and multiply this finding by 20 pounds.Torque wrenches are most commonly available with ¼-, ⅜-, and ½-inch drives; the latter two sizes are the most popular and versatile for automotive applications. A ¼-inch drive is commonly found on power tools and works well on small engines (like landscape equipment) and plumbing and HVAC components. With the information you have gathered, you can now calculate the applied torque of the wrench using the formula Ta = Ts x (D1/D2). Ta is applied torque. Ts is torque setting. D1 is the distance measured in step 1. D2 is the distance measured in step 8. A range of up to 20 to 150 Nm is enough for small jobs. If you use a torque wrench more frequently – the range should be about 100-700 Nm. If you apply the force of 80 Nm, the tool should have the range from 20 to 150 Nm. The square head drive size While that level of torque isn’t strong enough for full automotive repairs, it is more than enough for fixing small engines. This affordable wrench has an accuracy rating of ±4 percent and sturdy steel construction. The handle has raised steel edges for better grip and control, and the beam and head of the wrench is chrome.
