The effect of lubricant on torque spec

i really can't speculate on a dozer machinery spec--but i would surmise that it would not be dependent on the lubrication of the threads--every mechanic would be using a different lubricant and amount applied My experience is with structural steel applications--our spec called for a 30000 lb load on a 7/8 diameter A325 bolt. we would take a load cell test each morning and calibrate a torque wrench for the number of foot lbs to achieve this tensile load with no lubricants--the contractor would always use an air impact wrench. I would take my manual torque wrench and calibrate it also, and then would spot check the contractors installations.
As long as you stay below the ultimate tensile strength of the steel bolt and be in the yield strength range it shoudn't matter much where you are--
does this make sense?? OM--your opinion please!

well what little i know about this is there a 30% difference between lubed and non lubed. so if your looking for 100 ft/lb when lubed it only takes 70 ft/lb to get the same stretch. but this has been when working with BIG stuff 2"-4" range bolts which where most of the time studs in drag lines not bolts. the rule of thumb is it would be a dry torque unless it tell you lubed it. now i know what kind of lube will change things. this is onsite passed down info so consider that when making your decisions as i have never read up myself. i don't know if i answered your question or just made more points to question's .

great tables! surprised at the big differential in the first table between lubricated and ant-seize

Thanks all. I torqued them to 100 ft lb ( with lube) . I will run the machine for a few hours ( someday......)
And the have Oilslick crawl under there and recheck them.

Glad I axed that question!

That seems low by either chart using lubed threads.
