Details & specifications.

From the maker · OMG Roofing Products’s description

OMG Polymer GypTec fasteners are glass-filled nylon auger fasteners with a 1 in. head designed to secure insulation and single-ply membrane to gypsum and cementitious wood fiber decks such as Insulrock, Permadeck, and Tectum. Sold by the box in lengths from 3 in. to 9 in., with 250 or 500 fasteners per box.

Coverage & How Much You Need

Each box holds 500 fasteners in the 3 through 7 in. lengths and 250 fasteners in the 9 in. length. Coverage depends on the specified fastener density; at a typical attachment pattern, a 500-count box covers a proportionate number of fastener positions.

Fit and Compatibility

Engineered specifically for gypsum and cementitious wood fiber decks such as Insulrock, Permadeck, and Tectum; it is not a metal-deck fastener. Select length based on insulation thickness plus deck embedment, and confirm your single-ply membrane system accepts polymer fasteners.

Key features

  • Corrosion-free nylon: Glass-filled nylon construction eliminates corrosion entirely.
  • No thermal bridging: Nylon material eliminates thermal bridging and condensation at the fastener.
  • High tensile strength: Glass-filled nylon yields high tensile strength for demanding roof assemblies.
  • Strong pullout and shear: Thread design and large root diameter provide increased pullout resistance and increased side shear strength.
  • Wide head: A 1 in. (25 mm) head gives broad bearing over insulation and membrane.
  • Length options: Available in 3, 4, 5, 5.5, 7, and 9 inch lengths to fit different insulation thicknesses.
