1/2 impact wrench Torque Recommendation
Hi,
I'm new to air tools. I have a 1/2 impact wrench with 300 pounds of torque--max. I am thinking I need another one with a higher rating for those tough lug nuts for example. Any torque recommendations 500??? more??? Thanks |
The majority of lug nuts should never exceed 100 ft lbs. (at least on aluminum rims like on a Corvette). I think on my C5 the specs are 85 or 95.
300 ft lbs is a tremendous amount of torque usually reserved for axle nuts, etc. |
Let me clarify. I am talking more about the torque needed to remove stubborn bolts/lug nuts, rusty bolts, etc. I am aware that I will probably never need that much torque to tighten bolts as you mentioned.
|
I got on of those 1000 ft/lb composite guns from Matco. It is BY FAR the strongest 1/2 inch drive gun in the dealership.
|
WOW Matco It must have cost a 1,000 bucks too!
|
Sorry, I don't use an impact wrench on anything.
If I take a vehicle in to have work done, I will tip them $20.00 or so not to use one. |
Having worked for the Tool division of Ingersoll-Rand in the past, I could be biased, but the new 2135TiMax is an awesome tool.
http://www.irtools.com/2135TiMAX/ I can probably get them for a very good price as well, maybe a little over $200. Shop around, they are all over the internet. I also have a 231 which is a very good tool for the money, probably around $100. |

Ingersal-Rand 244, if this won't knock it loose you need to be using a 3/4 drive gun. The composite guns are great if you like numb hands. (don't weigh enough)
1/2 drive has it's limits, but the 244 has yet to fail me. |
Yes, get a 500# 1/2" inpact, you'll use it a lot. A 300# is considered pretty weak. Just because it's 500#'s, doesn't mean you should crank down your lug nuts to 500#'s, you should use a torque wrench to torque them down to 100#'s. But when removing them, it will take a whole lot more than 100#'s.

I've got a IR 2131. Alway's been happy with it.
They have since replaced it with the 2135TiMax http://www.irtoolsales.com/ingersoll...impactool.html |
