Risky. Impact guns are by no means created equal; the good ones can deliver SEVERAL HUNDRED ft/lbs. of torque...whereas maybe yours tops out at 175. Regardless, these nuts are one of several that should be tightened to a specification - which you only get reliably with a decent torque wrench.Hopefully I didn't over tighten them since I used the impact to put them on until they stopped moving. Took off the impact as soon as I saw them stop. When I checked the torque specs, the torque wrench clicked immediately at 150 ft-lbs.
Further - and please know that I am not accusing you, but - many people believe that if you put a torque wrench on a fastener that was secured by a tool other than that torque wrench (as you did) - and it clicks - you have verified the torque. Not so. All that does is verify that the fastener is AT LEAST that tight. But who's to say it isn't actually 25% or 75% or 150% HIGHER?
Very risky - not just for over-tightening, but also for stripped threads! Imagine how inconvenient THAT would be!
