Features & Benefits
- The OMG Purlin Fastener drills through up to 12 gauge steel in seconds.
- The 3/4-in. drill point allows the fastener to be drilled through the purlin before the threads engage into the the standing seam metal roof.
- Low profile hex head has a smooth surface to prevent damage to the membrane.
Product Use
OMG Purlin Fasteners must penetrate the purlin a minimum of 1-in. This ensures a minimum of 1/4-in. thread penetration into the structural member. 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.
Prior to job start, contact OMG to perform a pull out test to determine deck suitability and pullout values.
Note: Caution should be taken not to overdrive the fastener causing stress plate surface to deflect more than 1/16-in. Prior to job bid, contact OMG to visit the job site and inspect the deck.
