Connie, As usual, you are a wealth of very cool information. My rationale for lubing (or antiseizing) nuts is more prosaic: If it works for head bolts, main and big end bearings, it will probably work for lug nuts, gorilla mechanics with air wrenches not withstanding. Loose bits inside an engine gets catastrophic in a hurry. My education in mechanical fastenings is that you want to exploit the elasticity of the metal in order to gain holding power. Wheel studs are high grade steel, hence they can take a lot of torque which will resist vibration and loosening. I assume vibration is the ultimate culprit.

The automobile people are against doing that because they say then mechanics with air guns can over torque the wheel nuts, which could lead to stud failure. My rational is, I want grease in the threads because I'm submerging the wheels in water on launching and retrieving, and I don't want water in the threads while the trailer isn't moved and used - or has the lug nuts removed - to keep rust from forming there. My new Shellback trailer had been immersed in water since new with no protection, and the lug nuts were totally unmovable. It took my welding shop's air tools plus welding torch heat to get them to loosen up. I had tried for days using KROIL and other penetrants and got absolutely nowhere. Now they too are covered with water pump grease. Checking the tightness of lug nuts should be done before each trip - and during a long trip - but when I want them to loosen, without calling in King Kong for assistance, I'll rely on a bit of grease on the threads. Another thing to consider is to use tallow, but that is hard to obtain, unless you make it yourself (rendered suet). I used to use tallow on all my stainless turnbuckle threads on the Tripp-Lentsch - standing rigging and life lines - and never had a galling problem; ... and they always worked. Connie
