Application steps

APPLICATION

Sarnafastener #12 is fastened straight into the roof deck with a heavy duty (4 amp minimum), variable speed (0–2500 rpm), reversible screwgun with a clutch release and a #3 Phillips drive bit.

 

Sarnafastener #12 must penetrate steel decking and wood plank roof decks by 25 mm (1") and the underside of wood sheathing by 13 mm (1/2"). Care must be taken not to damage the roof deck. Choose the correct fastener length and do not overdrive or underdrive. Pullout tests are required prior to job start when used with existing wood sheathing roof decks for technical evaluation.
