Sarnafastener MAXLoad

Sarnafastener #21 MAXLoad is a threaded drill point fastener

Sarnafastener #21 MAXLoad is a threaded drill point fastener used within Sarnafil® roof systems to attach Sarnafil® S 327 Membrane into steel decking (22 – 24 gauge) or 1/2 – 5/8" (12.7 – 15.9 mm) wood decks.

  • Oversized roofing fastener with mini-drill point.
  • Extra sharp spade point for quick installation in new or reroof applications.
  • Pronounced buttress thread which increases both surface area and friction against the deck for excellent backout and pull out resistance.
