SUS 304 expansion screws are strong, rust-proof, and easy to install. They keep projects secure and long-lasting on concrete, bricks, and tough surfaces.

  • Material Quality: SUS 304 stainless steel resists rust and corrosion. It stays durable in wet or harsh environments.
  • Size & Length: Choose sizes like M6, M8, or M10 based on load needs. Longer bolts (60mm–100mm) suit thick walls or heavy tasks.
  • Installation Ease: Look for kits with nuts, washers, and spacers included. Pre-assembled parts save time and effort.
  • Load-Bearing Capacity: Thicker bolts (M10+) handle heavy-duty jobs like fences or AC units. Check product ratings for weight limits.
  • Expansion Mechanism: Double ball or three-piece designs grip walls tighter. Rubber sleeves add stability on uneven surfaces.
  • Corrosion Resistance: SUS 304 outperforms regular steel in damp areas. For extreme conditions, pick 316 stainless steel upgrades.
  • Application Versatility: Match bolt length to surface depth. Use shorter ones for walls, longer ones for concrete foundations.
  • Pack Quantity: Buy packs with 5–10 pieces for big projects. Smaller kits (2–4 pcs) work for quick fixes like toilet seats.
