so i bought the park chainring nut wrench because one of my chainring bolts (Sugino 75) kinda spun when i tried tightening it which made it impossible to tighten. when i tried to use the park chainring nut wrench the teeth on the tool didn't match up with the back of the Sugino 75 bolts...also, somehow while trying to tighten the bolt down the bolt got stripped. So i have 2 questions. 1. i have only seen the park tool and a shimano chainring nut wrench but is there one specifically for Sugino? 2. I haven't really had to consider this before but because of this problem i'm facing i'm wondering if Sugino 75 chainring bolts are replaceable with other chainring bolts or can i just use any chainring bolt (single chainring bolt of course)?
