I have replaced hub bearing bolts with 10.9's. Most hardware stores have standard 10.9's which when accompanied with a proper washer will work fine. I prefer using flange bolts whenever possible for replacing hub bearing bolts. 9 times out of 10, the OE bolts were flange bolts. Flange bolts have a larger grip area than regular old hardware store bolts. The larger the grip area, the more likely it will hold torque. Auto parts stores, hardware stores and fastener stores should have flange bolts readily available in the size you need.
