I'm with Jerry Shafer on this one. S-5 clamps with rails work well
without punching holes in the metal roof. If the roof is fastened well
to beefy steel C channel it should be fine. The S-5 clamps themselves
are stronger than the roofing.

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

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

There is a glaring lack of good options for 5V metal roofs in Florida.
Sure, there are some butyl tape based attachments that penetrate the metal,
but what happens when the truss lands below a V-crimp? The only real option
is a deck mount solution or truss blocking (which is excruciating in a

Why puncture the metal can't S-5 be used.

Jay,
I researched this years ago, so I have no specific figures for you such
as pullout strength, only the general lesson that I learned. The pullout
strength of Tek and similar self-tapping screws is surprisingly high,
especially in the larger diameters, such as #14, which equates to 1/4"
as

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 wo
I think there is a jumper in the FM100 that will allow the Mate3s to
communicate with it. I don't remember off hand where it is and am not at a
computer with that info, but maybe this will prompt a look at the manual to
see if they mention it.
