10d Common Nail

[GSEngineer]

Does anyone know the shear strength of a 10d common nail? Is there a website that might list such capacities?

See NDS, Chapter 11.

The shear strength of a nail is kind of meaningless in a vacuum. The geometry, side member and main member properties are important.

Note that the NDS does not specify and ASTM standard for nails. It's up to the designer to do so.

Nails are made of steel. If they were used to connect steel, shear strength would be a consideration, but they are used to connect wood.

And watch out, 10d is not a unique designation either. 10d "box", "sinker", "common" and those shot out of nail guns can all have different shank diameters!

What Hokie says is correct. I love how he said it.

You will find allowable lateral bearing loads and withdrawl loads in various tables based on the nail size, depth of penetration, the wood species, and type of connection, but no general number for shear for the nail alone as the lumber is critical and there are just too many variables. If you need that, for whatever reason, you will have to calculate it based on the area and allowable shear stress for the nail.

If you can get your hands on it, check for these allowable values for pullout and lateral bearing in the "Western Woods Use Book", or similar publications.

As PMR06 says, there are many different nail sizes for the given name. I usually will call out the nail as 8d (2-1/2" x .131") to help clarify specifically which nail I am talking about.

I suspect you are interested in lateral resistance, not shear strength. The Wood Design Manual published by the Canadian Wood Council includes factored lateral resistance for various sizes of nails in D. Fir, Hem. Fir and SPF.

In the U.S.A., a 10d common nail has a length of 3" and a diameter of 0.148". There are several charts available on the internet. Try the following link:

Attached is a report on frv and MS's topic

Also review NDS-2005, Table 11N COMMON WIRE, BOX, or SINKER
NAILS: Reference Lateral Design Values (Z) for Single Shear (two member) Connections for sawn lumber or SCL with both members
of identical specific gravity (page 97)
