The yellow zinc coating delivers excellent corrosion resistance, making them suitable for both indoor and outdoor construction projects.
Advantages:
Stronger holding power with large nail heads
Prevents sinking and cracking on wood surfaces
Corrosion-resistant zinc coating for long-lasting durability
Compatible with most standard coil nailers
Applications:
Large head coil nails are widely used in pallet and crate manufacturing, plywood and formwork installation, furniture assembly, siding, roofing, and general construction projects. Their reliable performance makes them an ideal choice for woodworking factories, packaging industries, and building contractors who need efficiency and durability in bulk fastening solutions.

Applications of Large Head Coil Nails
Large head coil nails are widely used in industries that demand extra holding power and reliable fastening. Thanks to their enlarged head and durable coil design, they deliver consistent performance across a variety of applications:
Log Cabin & Wooden Structures: Ideal for timber framing and construction nails needs, providing secure fastening in log houses, cabins, and outdoor wooden buildings.
Asphalt Shingle Roofing: The wide head offers better surface coverage, preventing nail pull-through and ensuring long-lasting protection.
Wooden Pallets & Crates: As pallet nails, they are perfect for high-volume pallet manufacturing and heavy-duty wooden packaging, ensuring structural stability during transport and storage.
Wood Products & Joinery: Reliable for assembling wooden panels, boxes, and other wood nails applications that require durability and consistency.
Wooden Furniture: Excellent choice for furniture production, where strong fastening and clean finishes are equally important.
With their superior strength, corrosion-resistant coatings, and smooth feeding design, our large head coil nails help manufacturers improve efficiency and maintain high product quality in construction, packaging, and woodworking industries.
Difference Between Large Head Coil Nails and Standard Coil Nails
When comparing large head coil nails with standard coil nails, the main difference lies in the nail head size and its performance benefits:
Head Diameter
Large head coil nails: 9.0–10.0 mm, offering a wider surface area.
Standard coil nails: usually 7.0–8.0 mm.
👉 The larger head provides stronger holding power and reduces the risk of pull-through, especially in softwood or thin boards.
Holding Power
Large head nails are designed for heavy-duty applications such as pallets, crates, roofing, and log cabin structures.
Standard nails are more suitable for general woodworking, furniture assembly, or lighter construction tasks.
Applications
Large head coil nails: pallet nails, construction nails, roofing nails, log house nails.
Standard coil nails: furniture nails, box nails, woodworking nails.
What to Consider When Choosing！！！
Material Type: For outdoor or humid environments, galvanized or stainless steel large head nails are recommended to prevent rust.
Wood Hardness: Softer woods (like pine) benefit from large head nails because they distribute pressure better; harder woods may not always need oversized heads.
Load Requirement: If the project involves heavy load-bearing (pallets, decking, roofing), choose large head coil nails. For lighter or decorative work, standard coil nails are sufficient.
Tool Compatibility: Check that your pneumatic nailer supports the coil angle (14°–16°) and nail head size to avoid jamming.
Choose large head coil nails when you need maximum holding strength and pull-through resistance, especially in construction and pallet manufacturing. Use standard coil nails for lighter woodworking and furniture production where efficiency and aesthetics are more important.
Nail Gun Differences for Large Head Coil Nails vs Standard Coil Nails
When using large head coil nails, it is important to choose a coil nail gun that is specifically compatible with the larger head size (9–10 mm). Unlike standard coil nails, which can be used with most common nailers designed for 7–8 mm heads, large head nails require a gun with a wider magazine and stronger feeding mechanism to prevent jamming. They also demand slightly higher driving power, so a pneumatic nail gun with adjustable air pressure is recommended to ensure smooth penetration in both softwood and hardwood. Standard coil nail guns are more suitable for light woodworking and furniture assembly, while large head coil nail guns are designed for heavy-duty applications such as pallet manufacturing, roofing, decking, and log cabin construction. Choosing the right nail gun ensures efficiency, prevents misfires, and maximizes the holding strength of your construction nails.
