With annual exports of US$1-1.5 million to South America, Southeast Asia, Africa, and beyond, we understand the demands of global construction projects.
Why Our Spiral Shank Nails Transform Plywood Assembly:
- Advanced Thread Design: Spiral grooves create friction locks within wood fibers, reducing loosening under vibration.
- Corrosion Resistance: Electro-galvanized coating options protect against rust in humid environments.
- Material Efficiency: Requires fewer nails vs. smooth shank types due to enhanced grip strength.

Frequently Asked Questions:
Q1: How do spiral shank nails prevent plywood separation?
A: The helical threads act like screws, creating continuous friction against wood fibers. This mechanical locking resists forces that cause smooth nails to back out.
Q2: What coating is recommended for outdoor plywood furniture?
A: Electro-galvanized coating provides effective corrosion protection for exterior applications exposed to moisture.
Q3: Can I use these with standard nail guns?
A: Yes, they are compatible with most collated nail guns. Confirm magazine compatibility for specific models.
Q4: Do you offer smaller diameters for delicate trim work?
A: Yes, diameters down to 1.6mm are available upon request for fine woodworking applications.
Q5: What’s the minimum order quantity?
A: MOQ starts at 500 cartons but can be negotiated for sample orders or new partnerships.
Q6: How are shipments packaged?
A: Standard packaging is 5kg cartons with inner plastic bags. Palletization options are available for bulk orders.
