Features & Benefits

Features & Benefits

  • Can be installed into cementitious wood without predrilling.
  • 6 Lobe (T40) drive enhances installation and minimizes cam-outs.

Product Use

Product Use

Prior to job bid, contact OMG to perform a pullout test to determine the pullout values. 

The OMG Lite-Deck Fastener can be installed into cementitious wood fiber decks without predrilling. A pilot hole is required for gypsum, and hole size is determined by pullout results. The OMG Lite-Deck Fastener must penetrate the deck a minimum of 2-in.
Avoid overdriving the fastener and causing subsequent damage to the insulation facer.  Fastener must be tight enough so that the plate doesn't turn.

*Lite-Deck Fasteners can be used in lightweight structural concrete but are not designed for use in lightweight insulating concrete decks.
