Mazel electro-galvanized roofing nails with a wide flat head 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: 2"
• Shank: 11 gauge steel
• Head: large flat head seats shingle face flush
• Point: diamond point
• Finish: electro-galvanized zinc plate, intended for use under shingle cover
• Packaging: 50 lb box

Tip: 2" length is for re-roofing through one full existing layer of architectural shingles or for fastening into thicker sheathing or fiberboard. Drive heads flush with the shingle surface and not into it -- overdriven nails crush the asphalt mat and lead to leaks.
