Sheetmetal Screws

[BridgeBuilder88]

A co-worker of mine is having trouble finding information on sheetmetal screws regarding their strength, probably because they are used in places where the load doesn't come close to making them fail, like in sheetmetal.

Anyone have any insight into this? I'm not 100% sure what he's using them for, though.
