Hey all...it's rated for 1280 inch/pound torque...I'm guessing simple enough...divide by 12.

I just know it would be a possibly fatal mistake if I miscalculate...that's about 106 foot/pound torque...and lug nut torque specs are 88 ft/lb RIGHT!??! So if I torque my wheel locks with this, I'm good to go?

Just making sure. Got this for valentine day and am super excited I may not have to wait for the friggin compressor to fill up to do simple rotations etc.

Thank you!

Never rely on a impact device to "torque" bolts. You can tighten with, but ALWAYS use a torque wrench to get the accurate torque.

Depends.

You are correct to divide by twelve to achieve foot pounds, but be sure to check your owners manual or service manual to determine the correct lug nut torque values. Most are around the 100 ft/lbs range.

To be complete accurate, a good torque wrench should be used to affix wheels. Once during install, and again after a hundred miles. Do you have a torque wrench? Or access to one? Does the impact have a torque setting? Maybe use the impact first, and then use a torque wrench to see if it needs to be tightened further. If not, you're probably good to go. Remember, however, that over tightening isn't good either. Damage to the rim or even the brake rotor is possible (warping).


Edit: I see Kris already answered.

that reading is also at max battery power (im assuming that it is battery operated).

Still why not use a torque wrench?

Might damage the threads with over torquing.

Really?? That seems like a lot. I am not trying to say your wrong but I know at least Acura's service manual says 80ft/lbs and I think Toyota/Lexus is 75ft/lbs.

My Viper calls for 95. I do agree with you though in that 100 seems high for everything else . . .

Thanks guys...
I guess I swap rims and rotate and work on the car so much I was looking for the easiest way. Yes, it's a lithium ion battery powered one. I KNOW I probably overtighten by hand, I put the back ones on by hand and I couldn't get them off yesterday with the Impact driver...the fronts I had torqued down with the air impact gun on the highest setting and I was able to untorque it with the makita one. So...that said, i think on a full charge it probably OK to torque down. I'll know for sure by tightening with it then loosening by hand to see how easy it is to come off.

Didn't know about the warping rotors from overtorquing...that is great info.

You guys will get a great laugh...I NEVER have torqued anything. Ever...so finally I buy a torque wrench...set it to the proper 88 ft/lbs and BAM, break the wrench. Yeah...it was inch pounds...not foot. I snapped the tool in half! lol.

I should invest in one though.

The Makita Impact driver is great, I have one as well, but definitely use a torque wrench for tightening your lug nuts.

Thanks for the responses all...

Use a torque stick, not as precise as a torque wrench, but will help in keeping the lugs uniform.

Hmm...that's pretty cool. What's a torque stick?
