[RE-wrenches] Metal roof/self taping screws

Jay:



Look again.  There are fasteners for metal purlins.  One is the JT3-SB-8.0
with FZD sealing washer and the other is the JT3-SB-8.0 with storm washer.

Hi Jerry



I thought about it.

But they are $5 each

Not rated for L feet

Have 4 holes vs 1 hole

There is no underlayment as it’s a barn



Using polybutylene tape and or caulk, it’s a pretty solid way to keep water
out and with the self tapping bolts is more secure to me ( thanks Allan).



The parts that William suggested are designed for metal roof over wood
substructure, not applicable in this case.



I’ll just look for the right self driving lag bolt

What do people recommend for a metal roof ( with flat sections, not
corrugated)on 3/16” thick x 2” wide C channel for attaching L feet

Self taping fasteners would be the easiest. Doing a nut and bolt would be
possible but quite time consuming.
A machine self taping bolt and then adding a nut would be a lot easier than
nut and bolt.

But that is my question. Is a self taping screw enough or does it need to
be bolted?
