RetroDriller Fastener

The OMG RetroDriller Fastener is designed for attaching single-ply membrane systems to structural steel purlins (up to 3/16") in standing seam metal roof retrofit applications.

This fastener has a 1/2-in. drill point which allows the screw to quickly drill through the purlin before the threads engage into the standing seam metal roof.  This greatly reduces point burnout and breakage as well as eliminates "jacking" between purlin and standing seam metal.

The OMG RetroDriller Fastener is available in five lengths from 4-in. to 10-in.

Features & Benefits

  • The OMG RetroDriller Fastener drills through up to 12 gauge steel in seconds.
  • The 1/2-in. drill point allows the fastener to be drilled through the purlin before the threads engage into the standing seam metal roof.
  • Low profile head has a smooth surface to ensure that there is no damage to the membrane.
  • FM Approved.

Application

The OMG RetroDriller must penetrate through the purlin in a minimum of 1-in.  Using a screw gun with a maximum of 1800 RPM, drive the fastener through the purlin until a slight depression is seen around the plate.

NOTE: Caution should be taken not to overdrive the fastener causing stress plate and surface to deflect more than 1/16-in. Prior to job bid, contact OMG to visit the job site and inspect the deck.
