These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated woods. For applications in higher-exposure applications, consider type-300 series stainless-steel fasteners for superior corrosion resistance. See additional important information before selecting a fastener for a specific application.
Nominal Shear Strength (Rn) for Wind and Seismic Loads Shearwalls (Wind and Seismic Loads) Faced with 1/2" Gypsum Board (lb./ft.)
Nominal strength shall be multiplied by the resistance factor (Φ = 0.6 LRFD Seismic, Φ = 0.65 LRFD Wind) to determine design strength or divided by the safety factor (Ω = 2.5 ASD Seismic, Ω = 2.0 ASD Wind) to determine allowable strength.
For gypsum sheathed shearwalls, tabulated values shall be applicable for short-term load duration only (wind or seismic loads).
Gypsum board shall comply with ASTM C1396.
Gypsum board shall be applied horizontal with 33 mil strap blocking of 1 1/2" width. In addition, solid blocking is required between the first two end studs. Alternatively, sheets may be applied vertically or values can be multiplied by 0.35.
Studs and track shall be a minimum thickness of 33 mil.
