ring shank coil roofing nails

1-3/4 Inch (44.45mm) Electro Galvanized Coil Nails - 0.120" Shank, Full Round Head, 15° High Wire Collated for Asphalt Shingles & Insulation Boards

Product Overview

1-3/4 Inch Electro Galvanized Smooth Shank Coil Nails are specialized fasteners made of Q195 high-quality steel, optimized for architectural and woodworking applications such as asphalt roofing shingle installation and insulation board fixation. With a length of 1-3/4 inches (44.45mm), shank diameter of 0.120 inches (3.05mm), and 15° high wire collation, these nails are compatible with most mainstream 15° coil nailers, ensuring efficient, jam-free high-volume installation.

The electro galvanizing treatment forms a uniform zinc coating on the nail surface, effectively isolating the steel from moisture and chemical corrosion, thereby extending the service life of the fastener in indoor and mild outdoor environments. The full round head design provides a large bearing area to prevent pull-through, while the smooth shank reduces driving resistance, making it ideal for fixing wood, wooden components, asphalt shingles, and insulation boards in construction, furniture manufacturing, and woodworking projects. Packaged as 120 nails per coil and 60 coils per carton (7,200 nails total, 18.6kg), the product meets the demand of large-scale construction tasks.

Core Selling Points

• Precise Dimension & Material Quality: 1-3/4 inch length × 0.120 inch shank diameter, made of Q195 steel with excellent toughness and strength, ensuring stable fixation without shank bending during driving.
• Electro Galvanized Corrosion Resistance: The zinc coating provides reliable protection against moisture and mild chemical corrosion, suitable for indoor and dry outdoor applications (e.g., roof insulation boards in non-coastal areas).
• Full Round Head Design: The large head area distributes pressure evenly, preventing the nail from pulling through asphalt shingles or insulation boards under wind load or material contraction.
• 15° High Wire Collation: Ensures smooth feeding in 15° coil nailers, reducing jams during high-volume roofing construction and improving work efficiency.
• High-Volume Cost-Effective Packaging: 7,200 nails per carton, ideal for large-scale residential and commercial roofing projects, reducing the frequency of coil replacement and project downtime.

Installation Steps & Operational Recommendations

Standard Installation Process (For Asphalt Roof Shingles)

1. Tool Matching: Select a 15° coil roofing nailer; confirm the nailer’s magazine is compatible with high wire collated coils and 0.120 inch shank diameter.
2. Air Pressure Adjustment: Set the air pressure to 80-105 PSI—80-90 PSI for asphalt shingles (to avoid material cracking) and 95-105 PSI for insulation boards and solid wood components.
3. Coil Loading: Open the nailer magazine, place the high wire collated coil in the correct position according to the tool instructions, and lock the magazine to prevent coil displacement during operation.
4. Depth Calibration: Test fire a nail into a scrap piece of the target material. Adjust the depth control knob to ensure the full round head is flush with the shingle surface—over-driving will damage the shingle, while under-driving will reduce wind resistance.
5. Formal Construction: Position the nailer perpendicular to the roof surface, press the contact tip firmly to activate the safety mechanism, and pull the trigger. Maintain a 6-8 inch nail spacing for asphalt shingles and 8-10 inch spacing for insulation boards.

Key Precautions

• Do not use in coastal or high-humidity outdoor environments for long periods—the electro galvanized coating has limited corrosion resistance compared to hot-dip galvanized nails, and rust may occur under salt spray or prolonged rain.
• Ensure the nail penetrates the roof deck by at least 3/4 inch when installing asphalt shingles to guarantee structural stability and wind resistance.
• Store unused coils in a dry, ventilated warehouse with relative humidity below 60% to prevent the zinc coating from white rusting due to moisture.
• Wear safety goggles, non-slip work shoes, and a safety harness during roof installation to prevent falls and injury from flying debris.

FAQ (Frequently Asked Questions)

Q1: What is the difference between electro galvanized and hot-dip galvanized coil nails for roofing?

A1: Electro galvanized nails have a thin zinc coating (5-15μm) suitable for dry indoor/mild outdoor environments, with a lower cost. Hot-dip galvanized nails have a thick coating (≥85μm) with superior corrosion resistance, ideal for coastal or high-humidity outdoor roofing projects, but with a higher cost.

Q2: How many nails are needed for a standard residential roof?

A2: For a standard asphalt shingle roof, the recommended dosage is about 4-6 nails per shingle. A 7,200-nail carton can cover approximately 1,200-1,800 shingles, suitable for most small to medium-sized residential roofs.

Q3: Can these nails be used for insulation board fixation on interior walls?

A3: Yes. The electro galvanized coating is suitable for indoor dry environments, and the 1-3/4 inch length is ideal for fixing insulation boards to wooden wall studs—maintain an 8-10 inch nail spacing for stable fixation.
