[RE-wrenches] Metal roof/self taping screws

[Jay]

I just found a company that has a very large selection of self tapping screws and bolts. And lots of technical data.

https://www.dynamicfastener.com/wp-content/uploads/2020/04/2020-Hand-Guide-MAPP-small.pdf

This is the link to their catalog. 
Otherwise just lookup dynamic fastener.
