I had a WTB post in the classifieds but I've had a few PM's asking about it so I started a post here. This bolt was on the rear brake of my brother's Powell. Whether it is original or stock, I'm not sure. My machinist ID'd it for me this morning, calling it a "place bolt". From the brief research I did online, they are for applications where you really don't want the bolt to fall out, ie. flywheels, brakes, etc.. The design of the bolt has a cut underneath and around the underside of the head that gives it a slight "umbrella" shape. That relief cut partners with the grooves on top creating just enough flex on the head so that when it's torqued down it adds a bit of springlike tension and thus locking action.
I've seen the suppliers online but haven't found one that wants to sell less than 100. But, If it's not stock, than I'll slap in the normal hex head one I have and stop thinking about it. However, even if it's not stock...it sure looks cool! :thumbsup:
So... Do your Powells have one? :shrug:
