These are for our 5 bolt silver triple cranks, or doubles with a chainring guard. Stainless steel, so you won't strip them out like Will does with all aluminum chainring bolts. Torque spec is 8 to 10.5 nM.

The longer bolts are for triple cranks where the 74bcd holes are flush. The included 5mm spacers put the chainring out into the correct position. See our silver cranks for an example here. 

If you have a Sugino XD2 or similar crank in which the 74bcd bolt holes are raised, these longer bolts will not work on the small inner ring.
