HI Wally,
I"m wondering if somehow the label is listing NOCT instead of STC?

Thanks for the information, I really like these fasteners.
Bronze not stainless? We normally use stainless for everything. Given our
coastal location, we want to avoid corrosion.

The GRK fasteners mentioned in a previous post associated with the Ecofasten
flashing and L feet are self-drilling, but a pilot hole is still helpful in
some instances. Very nice structural fasteners – high quality stainless,
extremely course thread to increase pull out value and they use a T30

OK, got it.
The reason I asked, is some people in the past have used Isc and Voc to attempt
a power calculation. Obviously very erroneous results with this.
I agree that the labeling, as you've described it, is a bit misleading.
Perhaps they just had a dyslexic person running the labeling mac
I haven't read up on the mentioned structural screws yet, but do they
specifically state that they can be driven "without" a pilot hole? What is the
justification and how are they different so that they won't cause a board to
split under pressure?
Does anyone have some good info on this?

+1 on the use of structural screws. We ran an article about lag screws a couple
years ago:

One of the things that surprised me when I read this manuscript is how variable
lag screws are in terms of construction and quality. Besides th

improperly installed flashings doing more harm than good and the general
comments about L feet straight to the roof…
Yes, if you install ANYTHING wrong it's counterproductive but if you read the
instructions and use common
The EcoFasten GF1 flashing is easy to install on a retrofit and will not
necessarily add any height to the rail. If you do need to trim the
flashings installed around the skylight, then I would recommend adding
sealant to these penetrations. We ditch the included lag and use a 5/16"

I agree. I would drill a pilot for anything bigger than #12. 5/16" Lags get
a 1/8" pilot minimum.
Unfortunately, common 1/8" bits are usually pretty short and break off
easily.

Bronze Star Construction Lags are what I use. I usually use the 5/16" and
1/4" with the most thread I can into the truss without popping out the
other side. I have dropped to #7 with more penetrations if the truss
warranted it.

Hello Wrenches,
We are having a prolonged power outage due to the recent storm that
ripped through the eastern U.S., and people with PV systems are
contacting me about ways to harvest their solar. I'm investigating
inexpensive ways to at least let people have power during the day.

Bill,
Can you provide a link to the product you are using - I found a lot of
screws on that site but none called "structural".
Thanks

I don't believe you are correct here. The body of the lag does not do
anything for the holding power, it is the threads that prevent pullout. If
you drive a 5/16 lag into a 3 x 8 without a pilot hole, you will be putting
a lot of pressure into the wood to split it. It might not split every time,
it
Yep, a properly sized pilot hole is the key. As far as I know splitting of rafters has not been a problem for me; it's not always possible to get inside to see. When the lag tightens down and doesn't spin out, I assume it's good.
Maybe we have better quality building supplies in Indiana. A lot o
