Coverage & How Much You Need:
Fastener count per board depends on wind-uplift requirements and fastening pattern in the project specification; typically fasteners are placed per insulation board at the spacing the design calls for. Divide total fasteners required by the box count (250, 500 or 1000) to order the right number of boxes.
Fit and Compatibility:
Made for Sikaplan roof systems to attach Sikaplan Fastened or Sarnatherm insulation, Sarnatherm roof boards, gypsum roof boards or other Sika approved boards. Matching fastening plates, insulation and membranes are sold separately; use the fastener length that suits board thickness plus deck penetration.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match fastener diameter and length to the assembly, not just the deck: longer, heavier #15 fasteners handle thick multi-layer stacks and tall steel decks, while #12 suits thinner boards. Overdriving defeats pullout resistance, so set depth on the driver and pull a pullout test if the spec requires it. Keep boxes dry and unopened until install day to protect the finish.
Fasteners have sharp drill points; wear gloves and eye protection, and use the correct driver bit to prevent spin-offs and overdriving.
