Bluing nuts and bolts in oil, is it safe?
A few years ago, I heated up some exhaust bolts and quenched then in motor oil (under a fume hood). They still look relatively rust free despite the exhaust around them looking crusty from road salt. When I removed the nut and bolts, the threads were clean and the fasteners were removed with no effort.
Out of curiosity, I know that heating the metal and quenching it makes it softer. What is the risk of the bolt snapping off if I do this to oil pan bolts?

First, to address your specific concern: heating and quenching usually makes steel harder and more brittle, not softer —unless you are "annealing" it (cooling it very slowly)
Correct me if im wrong haha.
