What are the environmental requirements for storing self-drilling screws?

Storing self drilling screws does require careful consideration of environmental factors, as they directly impact the preservation quality, long-term stability, and performance of the screws. Here are more detailed requirements for storing them:

Firstly, humidity is a primary factor to consider when storing self-drilling screws. High humidity can lead to rust and corrosion on the surface of the screws, not only affecting their appearance but also reducing their mechanical performance and durability. Therefore, the storage environment should be kept dry, with humidity preferably controlled below 50% RH. If humidity levels are high, it's advisable to use professional dehumidifying equipment or desiccants to absorb excess moisture.

Secondly, temperature is also crucial for screw storage. High temperatures accelerate oxidation and aging processes, decreasing the lifespan of the screws. Conversely, low temperatures may cause the screw material to become brittle, impacting its performance. Hence, the temperature in the storage environment should be maintained within an appropriate range, typically recommended as 0-30 degrees Celsius.



Additionally, the storage location for self-drilling screws should have good ventilation. Well-ventilated environments ensure air circulation, reducing the accumulation of moisture and harmful gases, thus keeping the screws dry and clean.

Light exposure is another factor to consider. Direct sunlight can increase the surface temperature of the screws, accelerating oxidation and aging processes. Therefore, the storage area should avoid direct sunlight, and measures like curtains or sunshades can be used to block sunlight.

In terms of cleanliness, the storage environment should be kept tidy, avoiding the accumulation of dust, oil, or other contaminants. These pollutants can damage the surface of the screws, affecting their performance. Regular cleaning of the storage area is recommended to ensure the screws are kept in a clean, dust-free environment.

Attention should be paid to the storage method when storing self-drilling screws. Screws should be stored separately by size and type to avoid confusion. Special storage boxes or shelves can be used for storing screws, facilitating organization and retrieval. Additionally, screws should be stored in a stable manner to prevent collisions or external pressure that could damage their surface or affect their performance.
