When purchasing concrete screw, factors such as quality, size, and material will affect the use effect.
✅ Galvanized steel nails: rust-proof and corrosion-resistant, suitable for outdoor or humid environments (such as construction sites, exterior walls).
✅ Stainless steel nails: higher strength, acid and alkali resistance, but higher cost, suitable for special environments.
❌ Ordinary iron nails: easy to rust, only suitable for short-term or indoor use.
Length: nail penetration depth ≥ 1/3 of the nail length (such as fixing a 2cm wooden board, choose nails over 6cm).
Diameter: Thick nails have strong load-bearing capacity, and thin nails are suitable for fine construction (such as 1.8mm-4mm is common).
High carbon steel nails: high hardness, not easy to bend, suitable for concrete and brick walls.
Poor quality nails are easy to break or bend, affecting construction efficiency.
Smooth nails: easy to nail in, suitable for soft materials.
Threaded/ring nails: strong grip, anti-loosening, suitable for hard substrates (such as cement, gypsum board).
Choose regular manufacturers to avoid inferior products that cause falling off or rusting (such as well-known brands or factory direct supply).
Wholesale is more cost-effective, and you can negotiate discounts for large quantities, but don’t just go for cheap!
Test the nails before construction to check whether they are easy to bend or slip. When purchasing, look for regular manufacturers, the quality is guaranteed
