I looked it up:
Pop Rivets vs.
Bolts
These are two kind of arbitrary sources, but it shows that while rivets are not quite as strong, they're comparable. The steel 1/4" rivet (shear: 2750 lbs.) beats Grade 2 1/4" bolts (shear:~2200 lbs.). However, the higher grades outmatch the rivets by a lot.
If no hint or advanced BOM don't come out, will it make you not participate in FIRST this year?? - Elgin Clock [more]
