Coverage & How Much You Need:

A 3000-count bucket of 1 in. caps fastens roughly 15 squares of underlayment at 12 in. spacing (about 200 sq ft per 1000 caps); the 1-1/4 in. 2500-count bucket covers about 12.5 squares at the same spacing. Adjust spacing to local wind requirements.

Fit and Compatibility:

Use where cap-nailable underlayment, synthetic felts or housewrap is installed. For fastest installation, these caps suit cap nailers in the Stinger line; the nailer itself is sold separately. Confirm fastener length requirements with your underlayment manufacturer.

Expert Verdict Reviewed by the SuperArbor Pro Desk

Plastic cap nails are the standard for synthetic underlayment because the cap prevents pull-through and tear-out at high wind loads. Keep the 1 in. bucket for standard single-layer synthetic felt and step up to 1-1/4 in. where decks are uneven or thicker materials are used. On high-wind jobs, tighten spacing at eaves and rakes per the underlayment manufacturer.

Wear eye protection when driving cap nails, and keep fingers clear of the cap when hand-nailing.
