Pro-Fit 1-3/4 in. Plastic Ring Shank Cap Nails, 100-Piece

The Pro-Fit 1-3/4 in. Plastic Ring Shank Cap Nails are engineered for securing roofing underlayments, house wrap, sheathing, polyethylene, and roll roofing. Designed with a flexible round cap head that conforms closely to surfaces, these cap nails help prevent water from penetrating beneath the cap. Featuring a deformed ring shank for superior holding power and an electro-galvanized finish to resist corrosion, each hand-driven cap nail comes pre-assembled as an integral nail-and-cap unit for quick and efficient installation.
