if you can drill thru the center of the broken bolt with a bit aproximately 2/3 the dia of the broken bolt, untill the bit goes ALL the way thru then soak the $%^ out of it with FREEALL penetrating oil,(this stuffs amazing) this will allow the oil to soak in from both ends of the broken threaded section, let it soak at least 30 minute while you re-apply more spray oil every few minutes, then insert the easy out and gently twist the broken bolt remains out of the threaded hole, BTW heating and cooling the bolt, helps. heat with a propane torch the cooling it with the spray oil helps to lossen its grip on the threads if its really stuck :grin:

 

Okay how about tricks for keeping them from turning into the rusted ready to snap pieces of junk, in the first place?"

use grade 8 stainless and a coat of ANTISEIZE paste on the threads durringg assembly tends to prevent the problem

Move to the southwest where its so dry that 50 yo cars practically fall apart.

Antiseize helps in certain situations but with the salt they put on the roads in the winter here in the midwest, it seems like nothing can prevent rust.

 

graded bolts are only for steel bolts. allen bolts are generally grade 9, and stainless are in a class of themselves, somewhere close to a grade ~4 (if that existed..) IIRC.

but good tips, thanks.
