Any tips on replacing screws that hold coroplast to frame?

Thanks Tom- I will keep those fasteners in mind. I have the equivalent fastener but purchased at Menards. Probably cheaper weaker chinese quality. I too use the exact same 20v max dewalt impact driver (great tool) and the fastener drilling end just rounded off and didnt bite.

I've used several different styles/sizes of Fastenal's self drilling screws (mostly when I restored a pontoon boat) and the only time the screw failed to drill its own hole was when tried to use one on (unbeknownst to me) some hardened steel. I'm sure you know you have to kinda be careful with that Dewalt since it'll shear off a fastener due to the torque it can generate.

I bought a bag of 50 of these (3/8") in SSTL and the appropriate SSTL fender washers from Fastenal: https://www.fastenal.com/product/fas...ation=Material

The first couple I drilled pilot holes and my shoulders were wearing out from laying on my back and having to drill upwards. On the 3rd one, I said screw it (no pun intended) and just put it in the bit driver that was chucked into my Dewalt 1/4" impact driver ( This thing is a beast https://www.dewalt.com/products/powe...r-bare/dcf887b ) and in no time, that fastener had no issue in drilling its own hole and just zipped on in. From then on I did the same and didn't have one fastener that didn't drill its own hole. Put in probably 15 new and used the new SSTL screws in place of the original ones.

What size fastener did you use? Is 3/8 the diameter or length?

Thanks.
