Key Specifications to Confirm Before Ordering

To avoid size mismatch and production downtime, follow these core steps when confirming your order:

1. Measure the outer diameter of your paint tin body to match the crimping size of the neck base; common standard sizes range from 32mm to 70mm.
2. Confirm the thread pitch of your screw lid to ensure a tight fit: 4mm standard pitch works for 90% of commercial paint products.
3. Select the right surface coating based on your paint type: epoxy coating is required for corrosive solvent-based paints to prevent rust.
