Nov 23, 2003 · Re: 16D shorts-3 1/4" code approved Jim: Engineers usually call out nails that are common nails, because that's what the tables that they go by tell them. In the past we use to substitute box nails, then sinker nails, and now gun nails, but times have changed since everything we do has to be engineered.

Sep 3, 2013 · Re: GRK R4 Multipurpose screw vs. 16d framing nails Sure, all you have to do is prove to the AHJ that the screws are structurally equivalent or superior to the nails. They will likely require that you submit engineering data to prove it. The manufacturer may have that engineering data, call and ask them.

Jan 6, 2001 · Re: Common nails Vs sinkers Comparing nails to nails can be like comparing apples to oranges. A 10d common has the same diameter (0.148)as a cement coated 16d sinker and has the same shear values. A 10d common has a length of 3 inches and a 16d sinker has a length of 3 1/4 inches and are "usually" interchangeable.

Sep 29, 2005 · Re: 16 d shear - The why of question asked. Glenn: A 16d common is 3.5x.162 while a 16d sinker is 3.25x.148 Simpson With the prevalence of gun nails today, the engineers should really be calling nails by diameters rather than penny weights.

Oct 19, 2004 · This discussion came up recently with another experienced framer and I told him that I would "ask" the JLC forum users. Our local building code requires 2 16d nails when end nailing studs to the top and bottom plate. It does NOT specify 2x4 or 2x6. What is your opinion and why regarding end nailing 2x6 studs? TWO or THREE 16d nails. THANKS!

Oct 2, 2005 · Re: 16 d shear - The why of question asked. 16d sinker/cooler nails are the same size and strength as 12d common nails but they have a smaller head that is usually tapered on the bottom with a checkered top. They are often vinyl coated for ease of driving or cement coated for pull-out resistance and used for framing where 10d or 12d common or box nails are …

Jan 15, 2006 · Re: shear strength of finish nails In 3/4" thick wood each side: Finish nails have about 2/3 the strength of common nails for the same penny weight size because their diameters are that much smaller. 8d common nail has a shear strength of 70 lbs. 8d finish nail is about 54 lbs 16d common nail is 96 lbs. 16d finish nail is about 62 lbs. These values can be increased …

Dec 20, 2000 · I keep seeing code nailing schedules calling for 16d nails to double plates and studs. What is the point of using 3-1/2" long 16d nails to join lumber that will end up 3" thick? Isn't it safer and more economical not to have nail points sticking through? Charles

Jan 16, 2006 · Re: shear strength of finish nails I would use a hardened screw, a #10, 4" long also 16d finish nails to install the door. Thats what I use for exterior doors when I get there to "adjust" them when the framer tacked them in through the brickmold.

May 10, 2006 · This schedule calls out 16d nails in general but in a footnote (1), which is for all nails, it says "Common or box nails may be used except where otherwise stated".
