Features & Benefits

Features & Benefits

  • The ½-in. length drill point allows the fastener to be drilled through the purlin before the threads engage into the standing seam metal roof.
  • Designed to reduce point burnout and breakage as well as eliminate "jacking" between purlin and standing seam metal.
  • Low profile head has a smooth surface to ensure that there is no damage to the membrane.
Product Use

Product Use

OMG RetroDrillers 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.
