An impact wrench needs about 500 ft-lbs of torque to remove lug nuts. In most cases, you will need the same amount of torque you used to tighten the lug nut in order to remove it. So, if you over-tightened it, you might need more than 500 ft-lbs torque.
What is a good torque rating for an impact wrench?
A minimum of 400 pound-feet of torque should give the power needed to remove lug nuts and perform most suspension work. However, if you live in the rust belt or near an ocean, you may want to consider an impact wrench with a torque rating of 500 pound-feet or more.

How much torque can a 1/4 drive take?
If you assume a reasonable quality tool steel that can handle 100K psi, a 1/4″ drive can take about 30 ft-lb, 3/8″ about 100 ft-lbs, 1/2″ about 230 ft-lbs, and 3/4″ about 800 ft-lbs. Really good steel will bump this up, while special tools like a wobble extension may cut it to half.What is a good torque for an impact driver?
Generally speaking, an impact driver with 1500–1800 in-lbs of torque puts more emphasis on higher RPM. It will do 95% of the work more quickly than a tool with more torque and slower speeds. Our rule of thumb is that, if you need to reach for a socket adapter, you’re better off grabbing an impact wrench.
How much torque does an impact driver have?The key to a cordless impact driver is torque. While an impact driver may appear similar to a drill/driver, it stands on its own with a strong power-train system that delivers nearly three-times more torque – up to 1,350 in/lbs.
Article first time published onHow do I know how much torque I need?
Torque is defined the length of the lever arm multiplied by the force applied. For instance, if you have a two-foot long bar and you hang a 10-pound weight from it, you have 20 foot/pounds of torque.
What is the highest torque impact wrench?
Our top pick is the DEWALT 20V Max XR Lithium-Ion Cordless Impact Wrench because it has 700 ft-lb of maximum fastening torque, 1,200 ft-lb of nut-busting torque, and a brushless motor that will extend its life.
