Lateral Force Resisting SystemsHold-down down hardwareLateral connection strengthdepends on:The Unified Structure• Crushing g( (bearing) strength ofwood• Size of wood pieces• Fastener size and strength• Plus appropriate end useadjustment factors (i.e. Wetservice, edge distance, end grain,etc.)The Unified StructureConsistency CountsWithdrawal ConnectionStrength Depends On:• Depth of penetration• <strong>Wood</strong> density• Fastener size and type• Plus appropriate end useadjustment factors i.e. wetservice, edge distance, endgrain, etc.• Nail sizes• Are you using the right nail?• Specify pennyweight, type,diameter and length• Ex: 8d common = 0.131” x 2-1/2”Type8d Nail SizesLength(in.)Wire Dia.(in.)Finish 2-1/2" 0.099Box & casing 2-1/2" 0113 0.113Siding 2-3/8" 0.106Cooler 2-3/8" 0.113Common 2-1/2" 0.131Ring- or0.120 or2-1/2"screw-shank 0.131
