I just updated the whole front end worth of bolts using stainless that were on the shelf at Fastenal...I think it cost me a whopping $8.00 or so...It was like 16 bolts that included the calipers. Don't use those black ones from the hardware store....just crap!
Stopped by Fastenal today. A box of 50 runs $13.00.
They only sell them in bulk. At $13 what the heck. I bought them. Thanks.
