About the product Interior electro-galvanized nails are designed for insulation fastening to interior attic and basement walls, felt-to-wood framing in interior roofing jobs, securing underlayment or subfloor plywood, and general indoor woodworking projects. #11 x 1-1/4" standard-point flat head nails Box includes 1 lb or approximately 207 shingle nails Ideal for attaching asphalt shingles, felt, insulation board, and more to wood framing Wide, flat head provides a larger bearing surface and a more secure hold Unlike hot-dipped galvanized roofing nails, these are intended strictly for interior projects where moisture is not present. Not recommended for exterior or weather-exposed applications. Instructions Line up your shingle on the roof. Place the nail just below the sealant strip. Hammer the nail in straight until the head sits flush. Make sure not to overdrive. Use 4 nails per shingle. Repeat for each row, overlapping as you go.
