Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use cap nails where code or manufacturer instructions require mechanical attachment of underlayment or insulation, and follow the required fastener spacing for your wind zone. Keep cartons dry and store them off the ground. If your project specifies a smaller cap or different shank, choose the matching PrimeSource cap nail size instead.
Cap nails have sharp points and edges; wear gloves and eye protection, and handle cartons with proper lifting technique due to the 50 lb weight.
