For those who prefer keeping it real when it comes to their Sugino crank arms, this is the same genuine Sugino hardware supplied with Sugino 75 & Super Lap bottom brackets, and are perfectly paired with Sugino Dust caps.

Of course, they'll work with any other square taper crank arm/BB combo that uses a standard M8 bolt.

Pro tip: put a drop of blue thread locker on the threads before installing to keep them from backing out on you and needing constant adjustment.
