Crank Bolt Type - 15 mm hex bolts used to be standard but some older TA, Stronglight and Zeus cranks used a larger 16 mm bolt, plus a few Japanese makers used a smaller 14 mm hex head. Allen key types were introduced in the 1980s and some are self-extracting, which means the crank removes itself when you undo the bolts.

Crank Bolt Thread - All square taper bottom brackets have a standard M8 x 1 mm thread, the only different thread types you’ll find on crank bolts are the much larger M12 & M15 bolts that are specifically for Octalink and ISIS bottom brackets.
