Stripped lug nut extractor1/17/2024 Since nobody is likely to do the work to get the right lubricated torque value, just DONT LUBRICATE YOUR LUG BOLTS. TL DR don’t use lubricant on your threads AND torque to manufacture spec. If you exceed the yield or ultimate strength of either the bolt of hub, it’s destroyed and requires replacement. ![]() Adding lube to reduce friction increases clamp force a lot and also makes the male/female threads much more stressed. In a general sense: input torque - friction forces = bolt preload to clamp parts. The mating threads would be obliterated as well. Learn how to remove stripped lug nuts from your car tires with the best stripped lug nut remover and extractor tools. If these threads were lbricated and then the monkeys who used an impact on the lug bolts, it would be far more disastrous than just an extraction kit and new lug bolts. It’s a hard problem to tackle without measurements, and the variations between lubricant application and torque application, it’s safer to just not use it. If, however, you were able to get the lug bolt ideal preload from BMW, then one could easily calculate a proper torque value to use with lubricant. As such, if using mfg torque specs then thread and conical surface lubricant shall not be used. Torque specs are defined per dry male and female threads. There should only be 1 school of thought on it. Great stuff but there are two schools of thought on using this on lug bolts. You only need one torque stick set to the torque spec of the BMW lug bolts, guessing it would be about 95 to 100 ft-lbs. Those f-fing morons should have used Torque Sticks when tightening your lug bolts, you cannot over torque when using the sticks, they are worthwhile purchase if using impact guns. ![]() Using a purpose-built extractor is the first and best way to remove a stripped lug nut. ![]() Very easy to find the Easy Out part and any auto shop can weld it on for a 12 pack of decent beer. Method 1: Making Use Of A Stripped Lug Nut Remover. It will cut into the lug bolt and allow you to remove it at home with a Gorilla Bar. Get an Easy Out (I could not find one deep enough to fit the lug bolt, so I made my own) and have it welded to the socket you remove the lug bolt with. I had a stripped lug bolt on an Audi two years ago and have a perfect solution that will coast about $40. Tried banging on a 16mm on top still nothing.Ĭalled a shop said they can try to weld on a piece. Im looking at suggestions on how to take them off? 3 of them when the wheels were installed they used impact gun full throttle and stripped 3.
