12" Polymer GypTec Fastener OMG GYPTEC120 for Gypsum & Tectum


The OMG Polymer GypTec® Fastener is a glass-filled nylon auger fastener with a 1-in. (25mm) head designed to secure insulation and single-ply membrane to gypsum and cementitious wood fiber (i.e., Insulrock®, Permadeck, Tectum®, etc.).

The fastener features a wide buttress thread design for excellent pull-out resistance, and tabs that lock the plate to the head of the fastener. The Polymer GypTec Fastener is designed to thread into the substrate but should not penetrate the deck. An internal 1/4-in. (6mm) square drive (driver bit included) assures fast and easy installation.

The Polymer GypTec is used with 3-in. (75mm) steel plates for insulation and 2-in. (50mm) steel plates for membrane attachment. The Polymer GypTec fastener is Factory Mutual and Miami-Dade County Approved.
Physical Data

  • Fastener Length: 12" (305-mm)
  • Thread Length: 2-1/4" (57-mm)
  • Thread Diameter: .675-in (15.12-mm)
  • Thread Per Inch: 3.5 Buttress
  • Head Diameter: 1" (25-mm)
  • Head Style: Internal 1/4" (6-mm) Square Drive (driver bit included)
  • Material: Glass-Filled Nylon
  • Weight 26 pounds


Features & Benefits

  • Thread design and large root diameter:
    – Increase pullout resistance
    – Increase side shear strength
  • Made from glass-filled nylon, which:
    – Eliminates corrosion
    – Eliminates thermal bridging and condensation
    – Yields high tensile strength
  • Non-penetrating design. Fastener threads into the deck but not through.
  • The OMG Polymer GypTec Fastener is FM approved for insulation attachment only.See system manufacturer for membrane attachment requirements.
  • 1/4-in. (6-mm) driver bit included in every box.Application
    • The OMG Polymer GypTec Fastener must embed a minimum of 1-1/2-in. (38-mm) (2-in. [51mm] is recommended, and required for FM applications) into the deck.
    • The Polymer GypTec Fastener can be installed into Tectum® decks without predrilling. A pilot hole is required for gypsum and some cementitious wood fiber decks (Permadeck, Insulrock, etc.). Use a 7/16-, 1/2- or 9/16-in. (11, 13 or 14-mm) drill bit, as determined by pullout test results. Pilot hole must be 1/2-in. (13-mm) deeper than embedment.
    • Note: Prior to job bid, contact OMG to perform pullout test to determine pullout values and pilot hole size. Also, care must be taken not to overdrive the fastener, causing subsequent damage to the insulation facer or single-ply membrane. Fastener must be tight enough so that the plate does not turn.


    Polymer GypTec Length Selection Procedure
    1. If applicable, determine the thickness of the existing roofing material.
    2. Add thickness of new insulation.
    3. Add 1-1/2-inch (38-mm) minimum fastener penetration (2-in. [51-mm] minimum embedment for all FM insulation attachment applications). NOTE:When predrilling, allow extra 1/2-inch (13-mm).
    4. If odd size requirement, always size up in length, not down.
    Plates & Accessories
    • Use 3-in. (75-mm) steel plate for insulation attachment. Use 2-in. (50-mm) steel plate for single-ply membrane attachment.
    Pilot Holes
    • Use a carbide tip drill bit for gypsum and cementitious wood fiber applications.
