Mazel electro-galvanized roofing nails with a wide flat head, smooth shank, and diamond point, sized for fastening asphalt shingles, roofing felt, and insulating board to wood roof deck. Steel core with a thin zinc electroplate finish for general weather resistance under shingle cover.

• Length: 7/8"
• Shank: 11 gauge smooth steel (~0.120" diameter)
• Head: large flat head (approximately 3/8" diameter) seats shingle face flush and resists pull-through
• Point: diamond point starts cleanly and minimizes deck splitting
• Finish: electro-galvanized zinc plate, intended for use under shingle cover; for fully exposed coastal or copper-flashed work, step up to hot-dip galvanized or stainless
• Standard: meets ASTM F1667 dimensional spec for roofing nails
• Packaging: 1 lb box

Tip: 7/8" length seats single-layer asphalt shingles into 3/8" plywood sheathing without poking through the underside; common on starter strips and short-run repair courses. Drive heads flush with the shingle surface and not into it -- overdriven nails crush the asphalt mat and lead to leaks. Six nails per shingle in normal wind zones, eight nails in high-wind areas.
