You can use the 3d printed ARC bolt covers to smoothen the transition between aftermarket chainrings and your Shimano cranks. Mount your standard chainring bolts (5mm hex bolt) as normal and press the bolt covers into place by hand.  The covers are specific to each location on the crankarm. They will not snap into place if you try to press them in an incorrect position.

If you are looking for an alternative to the ARC chainring bolt covers, have a look at the CNC machined R9100 bolt kit by TA Specialites.
