Expert Verdict — Reviewed by the SuperArbor Pro Desk
Select length by adding panel thickness to the required embedment in the deck, then pick the nearest stocked size. The washer-free pancake head speeds installation and reduces part handling on large nail base jobs. Keep a 6-lobe bit on the gun and replace worn bits early to prevent cam-out and head damage.
Wear eye protection when driving screws, and be careful with the sharp tips and edges of case-hardened fasteners.
Order Atlas Nail Base Fasteners in your length and keep panel attachment moving on your next roof.
