Say you dont use power tools or pneumatics. I hear/read an impact air gun is the best for removing subborn or stuck fasteners. Then you apply heat and penetrant for top of the line frozen fasteners. But what I am asking about is removing overly tight nuts and bolts with a regular wrench or ratchet.
Ok, so I go to remove my drain plug that is on there pretty tight. I can either, to exaggerate, put the wrench on the plug and tap it with a hammer to remove it. A sharp blow that is swift and delivers alot of torque for a brief moment.
Or I could lay into it with both arms and finesse it loose by slowly applying just enough torque to gradually loosen it (kind of the way you would tighten an oil filter).
So, I wonder which of these two, sharp and swift, or slow, smooth and gradual would be less likely to damage a fastener's threads by galling or stripping or whatever damage could occur. You can also comment on thoughts of the bolt head if you like, but I am most concerned with damaging the threads of the drain plug and the threads in the oilpan.
Thanks
