Dryness, ventilation, categorized storage, moisture and rain protection, and avoidance of corrosive environments are the core conditions for screw storage.
For ordinary hardware screws and high-strength bolts, the following points should be paid special attention to during storage:
Environmental Control: The storage environment should be kept dry, ventilated, moisture-proof, rainproof, and dust-proof to prevent moisture from causing metal oxidation and rust. Relative humidity should be controlled below 60%, and dehumidifiers or desiccants can be used as aids.
Categorized Storage: Screws should be categorized and stored according to type, specifications, material, and performance grade to avoid mixing and incorrect use. Divider boxes, drawer cabinets, or label boxes can be used for refined management.
Rust Protection: Choose surface treatment processes with thicker electroplating layers and longer salt spray test times (such as galvanizing or Dacromet coating) to enhance corrosion resistance.
VCI vapor phase corrosion inhibitor bags can be used for sealed packaging, especially suitable for long-term storage (more than 6 months) or transportation.
Physical Protection: Handle with care during storage to prevent damage to the threads; avoid contact with corrosive chemicals, and elevate the item using shelves to prevent direct contact with the ground.
Inventory Management: Establish inbound and outbound records, implement first-in, first-out (FIFO) systems, and conduct regular inventory checks to ensure inventory accuracy and efficient utilization.
