The Pro-Fit 1-1/4″ Hand Drive Roofing Nail packs 209 nails per pound — that coverage rate matters when you’re calculating job costs. Built from 11-gauge steel with an electro-galvanized finish, these nails handle Montana’s temperature swings without rusting out after one season. The 7/16-inch diameter flat head grabs roofing materials better than standard nails, and the heavy gauge resists bending when you’re hand-driving through aged lumber.
Skip these if you’re working with pressure-treated lumber. The electro-galvanized coating isn’t recommended for ACQ-treated wood — you’ll need hot-dipped galvanized or stainless for that application. But for standard asphalt shingles, roofing felt, and insulation board on untreated wood decking, they deliver reliable performance.
Heavy-Gauge Construction That Actually Matters
The 11-gauge thickness offers high resistance to bending during hand-driving. That’s not marketing fluff — it’s the difference between nails that mushroom when you hit a knot versus ones that drive straight through. Montana’s older buildings often have rock-hard lumber that laughs at thin-gauge nails. The round smooth shank combined with the diamond point penetrates roofing materials and wood substrates quickly.
The real advantage shows up in the coverage math. At 209 nails per pound, you’re getting approximately 1,045 nails in a 5-pound box or 10,450 in a 50-pound box. Compare that to lighter gauge nails that pack more per pound but bend like pretzels — you’ll waste less time straightening bent nails or pulling mushroomed ones.

Weather Protection That Works
The electro-galvanized coating provides protection against rust and corrosion in exterior environments. It’s not stainless steel, but it doesn’t need to be for most applications. For most roofing applications where the nail head stays exposed to weather, electro-galvanizing delivers enough protection to outlast the shingles.
The large striking surface on the head makes hammer driving easier — practical when you’re working overhead or at awkward angles. That bigger target means fewer glancing blows and bent nails. These nails are intended for hand-driving with a hammer or compatible non-collated pneumatic tools.
The limitations are clear: avoid these for pressure-treated lumber applications. The copper in ACQ treatment accelerates galvanic corrosion with electro-galvanized coatings. For standard wood roof decks and rafters with asphalt shingles and underlayment, they’re perfectly suited.
Installation and Compatibility
Drive these nails until the head sits flush with the material surface, following shingle manufacturer spacing requirements for optimal wind resistance. Beyond roofing, they work for securing vinyl siding and house-wrap to exterior wood sheathing.
The nails conform to ASTM F1667 standards for driven fasteners. National Nail Corp manufactures the PRO-FIT brand, and with a 4.6-star rating across 236 Home Depot reviews, field performance backs up the specs.
Packaging comes in 1-pound, 5-pound, and 50-pound boxes designed for jobsite storage. No fancy plastic cases or individual compartments — just bulk nails ready to work.
FAQ
What’s the actual coverage from a 5-pound box?
You’ll get approximately 1,045 nails in a 5-pound box at 209 nails per pound. Factor in some waste for bent nails or drops, but that’s your working number for estimating.
Can these be used with a nail gun?
Yes, they’re compatible with non-collated pneumatic tools, though they’re designed primarily for hand-driving. Make sure your gun can handle loose nails, not just collated strips.
Why shouldn’t these be used on pressure-treated lumber?
The electro-galvanized coating isn’t recommended for pressure-treated lumber. The copper in modern ACQ treatment causes accelerated corrosion. You’ll need hot-dipped galvanized or stainless steel nails for treated wood applications.
How do these compare to standard roofing nails?
The 11-gauge thickness and 7/16-inch head diameter provide greater holding power and bending resistance than lighter gauge options. You’re trading fewer nails per pound for durability and easier driving.
What’s the warranty situation?
There’s no specific manufacturer warranty — coverage typically falls under standard retailer 30-day return policies. These are consumable fasteners, not warranted equipment.
