WebMar 1, 2004 · Introduction. In the article "Attaching Deck Ledgers" (8/03), the authors used a procedure from the National Design Specification for Wood Construction (NDS-2001) to calculate the required on-center spacing of lag screws and bolts for deck-ledger-to-band-joist connections for various deck widths.Although the calculated spacings were "to code," … WebA lag screw can have as much as a nine times greater bonding factor to wood than a regular nail. If a lag screw with a 5/16-inch shaft is installed correctly, it can withstand pull-out, or …

WebTable 1. The tabulated allowable screw shear strength is applicable to connections where the shear plane passes through the smooth shank portion of the screw. Connections containing multiple screws must be designed in accordance with Sections 11.2.2 and 12.6 of NDS-15 (Sections 10.2.2 and 11.6 of NDS-12 and NDS-05 for the 2012 and 2009 IBC). WebThe figure below compares the NDS lag screw value, the tested lag screw value used in the 2009 IRC (source: 2009 IRC spacing values) and the Simpson Strong -Tie® SDS Screw. 1. 1⁄ 2" Lag screw shear design value based on Z perp per 2005 NDS.
