Kratos Roofing Nails 3 In Length Electrogalvanized 5 Lb Box Smooth Shank Large Head Fasteners (Diamond Point Outdoor Shingles Felt Underlayment)

Professional Grade Electrogalvanized Large Head Smooth Shank Structural Fasteners

The Kratos 3-Inch Electrogalvanized Roofing Nails are industrial-grade structural fasteners engineered for securing thick asphalt shingles, heavy roofing felt, and multilayered protective underlayment to exterior wood decking substrate boards. Fabricated from premium high-tensile carbon steel coated with a rust-resistant electrogalvanized zinc protective finish, these heavy-duty fasteners feature a broad flat head design and a smooth shank to handle the intense atmospheric stresses of outdoor weather-exposed wood framing. Packed in a convenient 5-pound bulk jobsite package, these 3-inch long architectural fasteners deploy deep wood penetration and a sharp diamond point geometry to solve the problems of loose shingle pull-through, high-wind displacement, and moisture-driven fastener oxidation lines.

Best Used For:

• Thick Shingle Installation: Anchoring architectural shingles or heavy multi-layered composite materials securely into timber roof decks.
• Weather Resistant Sheathing: Fastening structural roofing felt, synthetic underlayment sheets, and exterior vapor barriers without tearing.
• Outdoor Weather Exposed Framing: Completing external building envelope interfaces where long-term exposure to wind and ambient moisture is expected.

Key Performance & Safety Features

• Electrogalvanized Zinc Coating: Mechanically bonded zinc plating forms a protective barrier against localized humidity, water exposure, and oxidative rust.
• Oversized Flat Head Configuration: Enlarged outer surface diameter distributes clamping pressure uniformly to completely eliminate material tear-through.
• Engineered Diamond Point Geometry: Sharpened alignment point cuts cleanly through asphalt matrices and structural wood grain to avoid wood splitting.
• Sustained Smooth Shank Drive: Parallel shank profile reduces friction during hand driving or indexing to accelerate sequential field installations.
• 5-Pound Bulk Logistics Box: Sized and packaged to optimize transport layout and ensure contractors retain sufficient hardware volume for residential building bays.

Technical Specifications

Pro-Tip: When installing thick composite assemblies, drive the large flat head perfectly square and flush with the material surface. Avoid deep over-driving, as countersinking the head breaks the protective zinc boundary finish and compromises the wind-lift holding power of the composite sheet layer.
