Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use these fasteners wherever Hunter Cool-Vent or Hunter NB panels are being attached over corrugated steel deck of 16 gauge or heavier, and drive them until the star head seats flush without over-compressing the panel. Confirm pull-out values against your uplift requirements before final fastener spacing. Keep the included bits on hand at every gun, since the star/spider drive needs its matched bit to prevent cam-out.
Wear eye protection when driving screws; fasteners can deflect or break and steel deck edges are sharp.
Order Hunter Panels SIP HD Fasteners 4.5 in. for your steel-deck insulation attachment.
