How to Pick a Connector Series – Selecting Fasteners By Aram Khachadourian, PE, SE The parts won’t hold themselves up. They have to be fastened in place. In a previous entry in this series, Randy Shackelford, PE addressed selecting a joist hanger. This article focuses on the fasteners recommended for various wood connectors. For straps, holdowns, and other connectors, the first step is to specify a product that meets the load and corrosion resistance requirements. Then, specify fastening that is appropriate. The Wood Construction Connectors catalog, CC-2015, offers fastener information for every Simpson Strong-Tie connector used in wood construction. If you specify the type and number of fasteners and install them as shown in the catalog, then your installation will get full design values. Many connectors are designed to be installed with either nails or Strong-Drive® SD Connector screws. Some products must be installed with Strong-Drive SDS Heavy-Duty Connector screws. Figure 1 is a snip from page 76 of catalog C-C-2015. Here the face-mount hanger table gives the size and number of nails to be installed in the header and the joist, and the table note defines the nail size terminology. Let’s take a look at the various fasteners used for Simpson Strong-Tie connectors of all varieties. Figure 2 shows a scale view of almost all of the fasteners used with connectors. You can find this illustration in the Fastening Systems catalog, C-F-14, and the Wood Construction Connectors catalog, C-C-2015. However, we are continually designing, evaluating, and adding new fasteners to use with our connectors. Check our website for the latest and greatest. PHONE: 800-289-5627
