During my Perkins 4108 I have had to replace many bolts and studs and wonder if there are times when a bolt may be used to replace a stud.
Some components, of course bolt onto alloy castings and I can quite understand that a coarse thread should be used with a fine thread to actually fix the component.
I can also see how studs can help locate a component. On some fittings though I have found the studs a bit of a hinderance. some bolt/stud holes into the block are just blind holes and are UNF thread, by measuring the depth of hole I am able to decide on the bolt required and use that rather than a stud. In practice it seems to work ok and there is no exposed thread to go rusty. Now tell me …..what basic mistake am I making!!
