Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws and wood screws per the 2015 NDS. Both lateral (single and double shear) and withdrawal capacities can be determined. For a ball nut in compression, use the compression loading chart in Figure 9 to select a ball screw diameter that meets or exceeds the design load. Various types of screws ranging in sizes between No.8 and No.14 were used in the test program. Screws may be provided with the 4CUT™ or Type-17 point.
