Expert Verdict — Reviewed by the SuperArbor Pro Desk
Capped nails spread holding power over a wider footprint than bare nails, reducing tearing through underlayment and housewrap in high wind. Choose the 1 in. size for single-layer synthetic underlayment and the 2 in. size when extra embedment is needed. The welded head design guards against caps separating from the shank during driving.
Wear eye protection when driving cap nails with a hand or pole hammer, and keep fingers clear of the driving path.
