Fastening Systems - Drill-Tec Gyptec Fasteners

Drill-Tec™ Polymer Gyptec™
Fasteners



Product Description

The Drill-Tec™ Polymer GypTec™ is a glass-filled nylon auger fastener with 1” 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™ is designed to thread into the substrate but should not penetrate the deck. An internal 1/4” square (driver bit included) assures fast and easy installation.

The Polymer GypTec™ is used with 3” steel plates for insulation and 2” steel plates for membrane attachment. The Polymer GypTec™ fastener is Factory Mutual approved and available in lengths from 2 1/2" – 12”.

Application

Drill-Tec Polymer GypTec™ fasteners can be installed into some cementitious wood fiber decks without pre-drilling. A pilot hole is required for gypsum. Use a 7/16”, 1/2”, or 9/16” drill bit as determined by pullout test results. Pilot holes must be a minimum of 1/2” deeper than embedment. Polymer GypTec™ fasteners should be installed using a heavy duty variable speed screw gun. Installation at a low rpm is recommended. Minimum fasteners embedment into the deck should be 1 1/2” (2” recommended).

Note: 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.

Features & Benefits
  • Thread design and large rot diameter:
    - Increase pull-out 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 Drill-Tec™ Polymer GypTec™ is FM Approved for insulation attachment only. See system manufacturer for membrane attachment requirements

  • 1/4” driver bit included in every box


Plates & Accessories
  • Use 3" steel plate for insulation & 2" steel plate for single-ply membrane attachment
  • Use a carbide tip drill bit for gypsum and cementitious wood fiber applications
