GypTec Polymer Fastener

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

The fastener is used with 75 mm GypTec plates for insulation attachment and 50 mm GypTec plates for membrane attachment. Available in lengths from 60 mm to 305 mm.

Features & Benefits

Features & Benefits

  • Designed for increased pullout resistance and shear strength.
  • Made from glass-filled nylon, which eliminates corrosion and thermal bridging
  • Non-penetrating design. Fastener threads into the deck but not through.
  • Plate design locks onto the head of the GypTec fastener
Product Use

Product Use

OMG GypTec Polymer fasteners can be installed into some cementitious wood fiber decks without predrilling. A pilot hole is required for gypsum. Use a 11 mm, 13 mm or 14 mm drill bit as determined by pullout test results. Pilot holes must be a minimum of 13 mm deeper than embedment. GypTec Polymer fasteners should be installed using a heavy duty variable speed screw gun.

Installation at a low rpm is recommended. Minimum fastener embedment into the deck is 13 mm. The GypTec Polymer fastener should never penetrate the underside of the deck.
