We use the Simpson 1/4 by X" "Strong Drive" (SDS
series). We get them in the hot dip galvanize version. They
are readily available locally. I think building officials like the
Simpson name on structural products. They self drill and we have
had no instance of them snapping off while being driven.<br><br>

I didn't like it at all, it didn't go into the valleys like the old
mount, but drilled 4 holes into the side of the ridge, and just counted
on the roofing to hold the modules.<br>
I wanted to use the new ZEP rack, but never heard back from them, I guess
my project is too small (4 Kw).<br>
I'm going with SnapNRack blocks through the ridge top, and I'm going to
go through the purlins into rafters or 2x blocking as needed.<br><br>
Also, a related subject, I'm using the new HeadLok Lags from
FastenMaster. They claim to be stronger than a 3/8" lag, but
they have a 3/16"D shaft.<br>
I've had trouble with regular cheap Home Depot lags twisting off, so at
least these have actual strength ratings, and don't require
predrilling.<br>
They also have a no rust guarantee....<br>
Has anybody else used these? (or the similar Timberlok)?<br><br>
Thanks,<br><br>
