The main factors that affect the storage quality of self drilling screws

When it comes to the storage quality of self drilling screws, several factors need to be carefully considered to ensure the screws' performance and durability are maintained over the long term. Here's a detailed description of these influencing factors:

Humidity: Humidity is the primary adversary when storing self drilling screws. High humidity can cause rusting on the surface of the screws, which not only affects their appearance but more importantly weakens their mechanical strength and may even lead to thread damage. Therefore, the storage environment must be kept dry, with humidity controlled below 50% RH. If the humidity in the storage environment is high, it's recommended to use professional dehumidifying equipment or desiccants to absorb excess moisture.

Temperature: Temperature also significantly affects the storage of self drilling screws. High temperatures accelerate the oxidation process of screws, leading to material brittleness or decreased performance. While low temperatures may slow down oxidation, extreme cold can also cause material embrittlement. Thus, the temperature in the storage environment should be maintained within an appropriate range, typically between 0-30 degrees Celsius.



Ventilation: Good ventilation helps maintain the dryness and cleanliness of the storage environment. Poor ventilation can lead to the accumulation of moisture and harmful gases, accelerating corrosion and aging of the screws. Therefore, the storage location should have good ventilation to ensure air circulation.

Light exposure: Direct sunlight can increase the surface temperature of self drilling screws, accelerating their oxidation and aging processes. Prolonged exposure to light may also damage the coating on the surface of the screws. Therefore, the storage area should avoid direct sunlight, and measures such as curtains or sunshades can be used to block sunlight.

Dust and contaminants: Dust and contaminants can damage the surface of self drilling screws, reducing their performance. These pollutants may include dust, oil, chemicals, etc. Therefore, the storage environment should be kept clean, with dust and contaminants regularly removed.

Storage method: The storage method of self drilling screws also affects their storage quality. It's recommended to use dedicated storage boxes or shelves for storing screws, ensuring they are in a stable condition and avoiding collisions or external pressure. Additionally, screws of different specifications and types should be stored separately for easy retrieval and use.

To maintain the storage quality of self drilling screws, it's necessary to consider multiple factors such as humidity, temperature, ventilation, light exposure, dust and contaminants, and storage method. Only by ensuring these factors are properly managed can the performance and durability of self drilling screws be maintained over the long term.
