HOW TO CHOOSE THE RIGHT SCREW

2025-11-14
Selecting appropriate screws requires considering three core factors: application scenario, material compatibility, and specification matching.

1. Choose by Application Scenario

  • For wood or board connections: Use self-tapping screws. Their sharp threads can drill directly into wood without pre-drilling holes.
  • For metal part fastening: Opt for machine screws. They need to be paired with nuts or pre-tapped threaded holes for even force distribution.
  • For wall or concrete installation: Select expansion screws or chemical anchors. They rely on expansion force or adhesion for strong load-bearing capacity.
  • For thin parts or decorative fixing: Go for self-drilling screws. Equipped with built-in drill bits, they can penetrate thin metal, plastic, etc.

2. Pick the Suitable Material

  • Dry indoor environments (e.g., furniture, cabinets): Carbon steel screws are cost-effective and offer sufficient strength.
  • Humid environments (e.g., outdoors, bathrooms): Stainless steel screws (304 or 316 grade) resist corrosion and rust.
  • Non-ferrous metals or soft materials (e.g., aluminum, plastic): Copper or galvanized screws prevent electrochemical corrosion.
  • High-temperature scenarios: High-temperature alloy screws maintain shape without deformation under heat.

3. Match the Correct Specifications

  • Diameter: Choose based on base material thickness and load. Thicker materials or heavier loads require larger diameters (common sizes: M3-M12).
  • Length: The screw must penetrate the fixed part and embed deeply enough into the base material. For wood, it should be 3-5 times the screw diameter; for concrete, at least 20mm.
  • Head and drive type: Phillips drive or hex socket drive for easy disassembly. Countersunk heads hide flush with the surface, while pan heads offer better aesthetics.
