Default ATI pulley bolt, washer, and pin question

Do you know where I can buy these?
I think the bolt and washer can be bought at any hardware store (maybe) ... but where can I get the pin?
Thanks,
-Mike

Try EPP, don't even think about a hardware store bolt

Why? I can get grade 8 with washer ...
To me, the pin will lock the whole thing down so the bolt is just there to tight thing up together.
Just like the crank bolt, w/o pining the crank bolt, you will put down a ton of torque to keep it there. After pinning the crank bolt, it only needs 150 lbs of torque.
Thanks,

You need to find out if the ATI re-usable bolt is just a grade 8 or something more. The washer that comes with the ATI bolt is much more than anything you can buy at a hardware store. It's such a critical piece that I wouldn't skimp on it, IMO.

This is the only way to go, ive seen other peices used or not properly torqued and they will cause the pulley to go sideways killing the pulley and the belt.
