    A:  N8 is a designation number for this product. It is 1 1/2" long and .131" diameter. There are different lengths AND diameters designed to be used with their different products. Here is the link to the Simpson Strong Tie page for these nails. Check out the chart for the size you need: http://embed.widencdn.net/pdf/plus/ssttoolbox/esnaex65dw/C-F-2017-p338.pdf?u=gwur7r More info is on the Simpson Strong Tie Product Site, punch in the above number, click on the product, and you will see tech and product info to click on below that.

    A:  A confusing situation. Joist hangers are usually hung on 1 1/2" thick framing material. Therefore you only want 1 1/2" in length, but the diameter is the same as a normal 8d galvanized nail. You are correct, but the description for these nails needs to be such that you know the diameter and what it will fit. "d' or penny is the common trade nomenclature that is now used more for the diameter, in turn, an indirect reference to shear strength. Before the short hanger nails were made, the 8d nails were specified.and judged by inspectors. Diameter, or shear is that factor that makes them strong enough or suitable. Therefore, the reference to diameter. Sometimes the normal length interfered with other parts of the construction , think steel beam with 2x framing attached, and the short nail were made.

    A:  The dimensions on the label are correct: 1-1/2" long by 0.131" shank width. I used these when I installed my privacy fence along with the SS fence brackets.

      A:  Perfect fit, zero jamb issues. Strongly recommend!!

      by|Mar 9, 2019

        A:  What they mean is these nails are the same thickness (or gauge) as an 8d nail but only 1-1/2" long. As nails increase in length 6d vs 8d vs 16d, they also increase in thickness/diameter. These are a special purpose nail for use in joist hangers as the normal length 8d nails, which are 2-1/2" long, would extend completely through the joist by almost an inch. Normally a nail this length (1-1/2") would be smaller in diameter, but for this application, they want the sheer strength of an 8d nail, but without the normal length. So for the special purpose of nailing joist hangers, these are sold.

        Q:Which screw can be used instead of this connector nail? I'm attaching an SUL26Z Skewed left joist hanger to a 2" x 8" x 16" pressure pine treated joist.

        A:  The nails are 10 penny by 1-1/2". A #8 screw 1-1/2" could be used instead of the nail. Look for pan head instead of flat head (like drywall or deck screws). The screw heads will lay flat against the bracket.

            A:  "Joist hanger" nail is a generic term. The actual nail to be used depends on the specific hanger being installed. Most of our hangers require a full length 10d common (0.148" diameter x 3" length) or 16d common (0.162" diameter x 3 1/2" length) nail for full capacity. The required fasteners for the specific hanger are listed in the load tables in our catalog or on our website. Thank you!

              The Simpson Strong-Tie / Strong Drive nails connect my decking joists perfectly. The nail heads and shaft are made out of a strong no rust material that will withstand years of harsh climates.

              Needed these to attach reinforced galvanized bracket plates to an extension post on a mailbox post. Pre-drilling the holes helped these drive into the wood easily.
