im looking to change out my non critical bolts on my car to aluminum. is there a tool i can use so when i pull an oem bolt i can size it up to order the new ones correctly?

You can steal the little plate from Home Depot that they have mounted in the nut and bolt section to test for different sizes. I don't know, I'm sure there's a device out there similar you could buy. Just curious, what bolts are you looking at swapping and why use aluminum?

just buy a variety of nuts and figure out which one fits the bolt.

if you have a tap and die kit they usually have a thread measuring tool, it wont say the diameter of the bolt, but thats the easy part to find out.

imho, no offense, if you don't already know how to measure bolt sizes, i think you might just as well leave the oem ones right where they are.
