Manufacturing Process of Clout Nails

Wire Drawing: Premium low-carbon iron wire is drawn through calibrated dies for strict gauge consistency.
Nail Cutting: Automated cutters shear wires to precise lengths, ensuring uniform shank and tip profile.
Head Formation: A CNC-press flattens heads, strictly controlling diameter and thickness for optimal holding power.
Galvanizing: Nails are hot-dipped or electro-galvanized per ISO 1461 standards to ensure >220g/m² zinc layer, tested against ASTM B117 salt spray (≥48 hours).
Inspection & Sorting: Each batch undergoes dimensional inspection, XRF coating check, tensile shear test and batch marking, meeting ANSI B18.5 tolerances.

Black Clout Nails: Enhanced aesthetic, water-resistant oxide layer for exposed joins

Application Scenarios & Advantages: Where Clout Nails Excel

Roofing & Sheet Fixing: The broad flat head distributes pressure, crucial for bitumen/felt roofs to prevent tear-through. The zinc coating blocks corrosion in harsh weather.
Timber Framing, Joinery, and Carpentry: Small clout nails offer neat, flush fixings on thin sections or decorative work where minimal head projection is key.
Felt Nails/Felt Application: Special felt nails with extra-large heads enhance grip and wind resistance on underlayment layers.
Pallets, Cases, Furniture: Used for pallet cleats due to strong retention and resistance to vibration loosening.
Landscaping, Fencing, and Sidings: Clout nails are the fastener of choice when attaching wire mesh, batten boards, or cement sidings in outdoor projects.

Small Clout Nails: Versatile for trim, lightweight joinery, neat felt underlay installations

Case Study – Galvanized Clout Nails for Solar Roof Retrofit (Europe, 2023):
When a European EPC company retrofitted 15,000m² of roofing for solar panel installation, clout nails with ringed shank and 250g/m² zinc coating were preferred over screws or staples. Result: zero corrosion or uplift after 18 months of exposure, despite severe freeze-thaw cycles. Project Lead Feedback: “Switching to galvanized clout nails cut hardware cost by 26% and reduced install time by 37% vs screws.”

Frequently Asked Questions (FAQ)

Q1: What is the primary material for clout nails and why is it used?

A1: Most clout nails are made from low carbon iron wire as it provides excellent ductility for cold forming, good tensile strength (390–420N/mm²), and is highly suitable for galvanizing or surface finishing.

Q2: What are standard specifications and head diameters?

A2: Typical clout nails range from 20mm to 50mm in length with head diameters of 7.5–9mm. Specialty variants like small clout nails can be as small as 10mm with 5mm heads for fine joinery.

Q3: What is the difference between black clout nails and galvanized clout nails?

A3: Black clout nails are carbon steel nails treated with a black phosphate or oxide finish, mainly for indoor or temporary use due to moderate corrosion resistance; galvanized clout nails withstand moisture and are suitable for permanent, exterior applications.

Q4: What standards should clout nails comply with?

A4: International standards include ISO 898 for mechanical properties, ISO 1461 for zinc coatings, EN 10230-1 for construction nails, and ANSI B18.5 for dimensions.

Q5: How long do galvanized clout nails last in outdoor applications?

A5: With quality hot-dip galvanizing (≥220g/m² zinc), expected outdoor service life ranges from 17 to 30+ years based on climate, as attested by EN 9227/ISO 6988 test methods.

Q6: Can clout nails be used for felt or bitumen underlayment?

A6: Yes, specialized felt nails with extra-large heads provide secure grip for bitumen felts, preventing material pull-through and optimizing wind resistance on roofs (per FM Approvals Loss Prevention Data Sheet 1-49).

Q7: What is the preferred installation method for clout nails?

A7: Manual hammering is common, but industrial settings use pneumatic nailers with custom collated strips (EN 1629-2 compatibility). Ensure straight insertion, perpendicular to substrate, for best shear and pull-out values.

Conclusion

As industries move towards more efficient, sustainable fastening methods, clout nails – especially those made from galvanized iron wire – remain an exceptional solution due to their reliability, anti-corrosive toughness, and universal applicability. Whether specifying for roofing, packaging, or advanced construction assemblies, understanding precise technical, application, and sourcing parameters is vital for maximizing performance and cost efficiency.
