Grip-Rite 1-1/4 in. Grip-Cap Ring Shank Round Metal Cap Nails - 50 lb. Box
Grip-Rite Grip-Cap 1-1/4 in. ring shank round metal cap nails fasten underlayment, felt and insulation board.

- 1-1/4 in. Length: The 1-1/4 in. length is suited for fastening thin underlayments and felts over wood decks.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cap nails are the fastener of choice for securing underlayment against wind uplift because the metal cap spreads the load. Match the 1-1/4 in. length to thin felts and underlayments over solid decking; use a longer cap nail where insulation board adds depth. Follow the underlayment manufacturer's fastener schedule, typically tighter spacing at eaves and ridges.
Wear gloves and eye protection; cap nails have sharp edges and drive with force, so keep hands clear of the striking surface.
