The Insane performance hub uses two hardened steel pins and two receiver holes drilled into the crank to allow the hub to pin to the crank. Its a pretty secure fit, and adds a noticeable effort while tightening the center bolt, which is assuring.

Gintani's crank hub "pin" is a machined "lobe" which is part of the 1pc hub. Only one side of the crank snout is drilled and then filed down to fit the "lobe".
