OMG Roofing Products OMG Polymer GypTec Square Drive Fasteners, 3 in. to 9 in., Glass-Filled Nylon, Per Box
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.
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.
- Non-penetrating design: The fastener threads into the deck but not through it, protecting the deck underside.
- 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.

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.
Frequently Asked Questions (FAQ):
Q: What comes in a box?
A: One length of GypTec square drive fasteners: 500 pieces in 3, 4, 5, 5.5, or 7 in.; 250 pieces in 9 in.
Q: Which decks are these for?
A: Gypsum and cementitious wood fiber decks, including Insulrock, Permadeck, and Tectum.
Q: Will they rust?
A: No. Glass-filled nylon eliminates corrosion, which also removes thermal bridging and condensation at the fastener.
Q: Do they go through the deck?
A: No, the non-penetrating design threads into the deck but does not pass through it.
Q: How do I pick a length?
A: Choose a length that spans the insulation thickness and embeds in the deck without penetrating it.
Q: What drives them?
A: They use a square drive bit to match the 1 in. head.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
On gypsum and wood fiber decks, metal fasteners are prone to corrosion and can thermally bridge; GypTec's glass-filled nylon solves both while maintaining high tensile strength. Verify embedment depth against the deck thickness so the auger point stays within the deck, and follow the membrane manufacturer's fastener density. Use the 9 in. size for thick insulation stacks.
Wear eye protection when driving fasteners, and confirm the deck type before installation since these are engineered for gypsum and wood fiber decks only.
