    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.

Load Tables

Nominal Shear Strength (Rn) for Wind and Seismic Loads Shear Walls (Wind and Seismic Loads) Faced with 1/2" Gypsum Board (lb./ft.)1-6

  1. 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.
  2. For gypsum sheathed shear walls, tabulated values shall be applicable for short-term load duration only (wind or seismic loads).
  3. Gypsum board shall comply with ASTM C1396.
  4. 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.
  5. Studs and track shall be a minimum thickness of 33 mil.
  6. Table based on Table C2.1-2 AISI Standard North American Standard for Cold-Form Steel Framing-Lateral Design 2007 Edition with Supplement No. 1 and Commentary.
