Well, I’ve been all over town looking for some nails to use on a few cedar fence panels. I need to nail 3/4″ cedar pickets to 1.5″ cross bars.
I’ve been to 4 big-box stores, the local lumber yard and 3 hardware stores (including a specialty one). The only options I’ve been able to find that didn’t come in $125 bulk sizes are:
– 1.25″ stainless (ring shank) or
– 2″ double-hot-dipped galvanized.
I’m thinking a 2″ nail would be ideal in terms of holding power and not as likely to split the cross beams. However, I’ll probaly go with the 2.25 nails, as .5″ didn’s seem like much penetration into the cross beam.
Anyways, the reason I’m posting is to ask if there is a rule of thumb for picking out nails? How far should a nail penetrate the ‘holding’ substrate compared to the substrate being held?

darrel,
A real rough rule of thumb is you should penetrate the "holding substrate" by twice the thichness of what your holding......in other words for 3/4" pickets you would want to penetrate the rail 1 1/2". So nail length would be: 1 1/2" plus 3/4"= 2 1/4"
BUT in your case you would probably come close to poking out the back of the rail so 2" double hot dipped would be fine. I would even pre-drill both the picket and the rail with a 3/32" bit to prevent splitting. Hold the picket in place and drill through both.

"A real rough rule of thumb is you should penetrate the "holding substrate" by twice the thichness of what your holding......
never heard that before, when I nail two studs together together I use 3" nails not 4 1/2".
I do realize that you said "real rough" and also application is different.
I think you gave him good advice. cept I sure wouldn't want do all that predilling.

Not Geoff but I agree with him. Obviously framing is one of the exceptions. Go ahead and use those 4 1/2' and clinch them over (;-) toss out your prybars but hang on to the sawsall.
I used to have some engineering link that went into fastners that said the same thing. (not an engineer).

If I were doing what the OP asked about I would use the Paslode with the hotdip ringshanks,

The biggest framing nail that I use is a 10d. I used 12d framing in Cape Cod for face-nailing studs.Joe Carola
<<What rule do you use for framing when nailing 2-2x10's together for example?>>
Joe, not trying to be a smart azz, but...the rule of common sense.
I'm sure you remember when 16d's were nailed straight through 2- 2x's being nailed together, then people got smart and started using 12d (and they were more commonly avaiable) but installed at a toe-nail angle....now 10d straight through is common, no pun intended.
The use of the "real rough rule of thumb" needs to be applied with common sense as well, since obviously you don't want, or need, a nail protruding through the fastened members in your question.
Practices that were common in prior times have changed, some for the better, some not, applying a "rule of thumb" in any instance requires a little knowledge and a lot of common sense, and even a willingness to know when to ask for help.

I did use 12d nails when I framed in Cape Cod. What I was getting was that we use 10d nails for all framing and nothing bigger and it's code. We use 8d nails for toe-nailing studs. What is your code for framing?Joe Carola
Framer, I covered that in post 3 of this thread. we thinking the same thing
I do the same thing sometimes - read the post and respond without reading the others.

This time I did read your post but Goeff didn't respond to you so I posted basically the same question.Many times I don't read all the posts because there are to many to read.Joe Carola
"Many times I don't read all the posts because there are to many to read."
I jump in late sometimes too, long after the thread has completely changed topics lol View Image View Image
16d nails and clinch the ends.
So convenient a thing it is to be a reasonable Creature, since it enables one to find or make a Reason for everything one has a mind to do. --Benjamin Franklin
>>16d nails and clinch the ends. <<Every single nail that you shoot into when nailing 2-2x's together you do that too? Can't you shoot the nail on an angle? A 16d is 3-1/2". Is the width of the nail the reason for using a 16d, because it doesn't make sense to have to use a 16d nail when 1/2" of it sticks out the other end of 2-2x's and then you have to bend them over. If you use a 10d 3" nail, you don't have to bend anything over. I just don't see the reason even if it's code to use a 3-1/2" nail that's sticks out 1/2" bigger than the two boards your nailing together.Joe Carola
It's just that I tend to overbuild (also don't have a gun), and I'm told that clinching doubles the pull-out resistance.

I just don't agree with whoever told you about using nails so that they stick out 1/2" past the 2 pieces of lumber your nailing together is for pull-out resistance.Where can a double 2x top plate go, or 2-2x10's for a header go as far as pulling out? If that's the case everyone should be using nails 1/2" bigger than the boards your nailing together and then bending them over.Maybe it';s a regional thing.Joe Carola
In my case it's mostly that it costs nothing but a few seconds of time. And on a double 2x it does produce a more tightly bound beam, as clinching sort of levers the pieces more tightly together.

Goffery's rule is the one I've always heard. As the next guy points out, obviously framing is an exception.
As far as:

- 1.25" stainless (ring shank) or
- 2" double-hot-dipped galvanized.

You kinda lost me there a little... are the larger nails that you found 2" or 2.25"??? None the less, obviously the 1.25" nails aren't long enough. The professional fencing subs I hire use 2" nails for that application, particularly since the fence boards often aren't a full 3/4" thick. If you use 2.25" nails you may find that you need to drive them at an angle.
And around here it is a bit hard to find 2" nails. 2 3/8" are very common but the 2" you have to look for.
yea, I was typing late at night. 2.25 is what I have and they definitely seem to long. You are right...2" nails? They must be some sort of mythical fastener that only exists in science fiction, as I can't find them anywhere.So, ultimately, it looks like screws make the most sense. I was hoping I wouldn't have to use screws as that just makes for a lot more drilling, plus I now have to hide the screw heads a bit better. Oh well.
darrel,
A 2" nail (6d) is a commonly used nail and should be available anywhere in the U.S. I can find them in 1, 5, or 25# boxes at any lumber yard, hardware store or even the big box stores.
Geoff
You'd think that. I can't find 2" stainless or hot-dipped anywhere around here, though.
Many of the "deck" and structural screws are selfdrilling..
.
A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
Stainless steel screws are available with pre-painted heads. One brand that comes to mind is Headcote.
2" SS screws. Mo betta.
Lots of factors involved. Eg, with the fence, the rails rarely lay tight against the posts (at least not for very long), so you need to allow another 1/4" or so there.
I think most folks just go with what "feels right". For thin materials a fastener that's 3x the first layer thickness (2x penetration) is about right, but you start dialing back at an inch or so penetration. For drywall using too long a fastener can lead to nail pops, oddly, so staying close to an inch is important.
Hard to believe that you can't buy a wider variety of nails in small quantities. Both HD and Menards here sell most sizes/types in 1# to 5# boxes. Check some of your local HW stores.
Dan:The issue is that I can find most sizes in steel, aluminum and zinc, but NOT stainless. The HD's around here don't carry stainless at all for some reason. The Menards only seem to carry one box at one size per store if you are lucky. At least with HDs you can assume they all carry the same thing. Menards seem to change inventory from store to store, though.I'm finding it very odd that there's so much ACQ lumber in these places now and so few fasteners for them.I ended up going with ACQ rated pre-colored screws. Took longer, but likely the best option.
Paslode has 2" ring shank galvanized nails that I have used on 3/4" fencing and they really hold. If you have a Impulse or air nailer they go up pretty fast and no pre- drilling. They do set-in a little, so a slight angle works the best so they dont poke through the 2 x 4.
