Nothing good ever happens when you've got damaged hub mounting bolts. First of all, you won't be able to notice it right away as the damage will build up gradually over time. You might notice your vehicle's handling slowly deteriorating every now and then. Worst of all, a single bolt could break and you won't even notice it since the remaining bolts will try to compensate. The best thing that you could do is to simply take a look at your vehicle's hub mounting bolts at the first sign of trouble, and prevent it from getting worse by replacing them right away. You won't have a hard time getting the right bolts for your car, and most shops have plenty of stock online.
Before you order replacement hub mounting bolts, it's important that you take a look at your wheels so you could buy the right amount from your trusted store. There are smaller wheels that will only require 4 bolts to hold them in place. For bigger vehicles, there are wheels that will require as many as 8 bolts on them. Check your wheels and order the necessary amount, or even stock some extra bolts as spares in case of an emergency.
You'll also have to make sure that you get the right sized bolts for your wheels, or they won't lock in tight. Check your car's manual and find out if it has information about your hub mounting bolts. Most manuals will have the part number listed and you could simply relay this to your favorite vendor. You don't need hub mounting bolts with special features or anything. You simply need one that'll fit your wheels. You won't have to spend a lot either as most bolts typically cost around $3 to $5 per piece.
