The Simpson Strong-Tie MDSS96 surface spline strap is 95-1/2" long, is attached with Strong-Drive® SDS Heavy-Duty Connector screws (SDS), and is an ideal solution for CLT diaphragms. For CLT manufacturers, it reduces costs by eliminating or reducing time for milling at panel edges. Since our tabulated values are based on tests, not just calculations, designers can value-engineer a solution using fewer screws than calculated solutions would allow. If nails are preferred to screws, we’ve tested our CMSTC16 strap with 0.162" x 2-1/2" nails. This solution has the added benefit of a low profile, which may eliminate the need for milling at panel edges. If plywood surface splines are preferred, we’ve tested with our Strong-Drive SDWS Timber screws for this application.
