Use of pop-rivets?

[Tom Bishop]

A bit off topic, but does anybody know a good supplier for aluminum bolts? Mcmaster is the only place that sells them that I can find, but they are almost 50cents a bolt and only offer a few sizes. Just by using them on our wheels this year, they save more weight than you might think. Thanks!

Mcmaster has a good supply of 1/4" 20 hex bolts that are not unreasonable. Lengths range from 1/2" to at least 4" and you can get longer but they won't be fully threaded. Once you go over that size they get a bit pricey, but 1/4" is plenty big for most fastening applications. That's our standard size bolt.
