My vehicle is a 1997 Nissan Pathfinder and I recently had to get my front wheels road force balanced to solve a shimmy issue with highway driving. But aside from that, the tech manage to strip a lug nut by over tightening with the gun. I got a replacement at AutoZone for now, but are aftermarket lug nuts a safe and good option? I got Dorman brand. I am thinking of replacing all lug nuts on the vehicle as I know they have been overtightened several times by shops, even by Nissan. I always torque it down to the specified 87-100 ft lbs, but I guess nowadays its hard to find people who dont take short cuts.

Do lug nuts ever need replacing due to age and over tightening on several occasions despite looking just fine? Should I replace mine? 

Thanks
