Advantage:
Grade 10.9 Surface Finish Blue And White Zinc Pan Head Screw
The surface zinc layer isolates water vapor and oxygen, making it suitable for humid environments such as bathroom furniture and outdoor scaffolding. It has a lifespan 3-5 times longer than ordinary steel screws.
Economical and practical
The price is only 1/3-1/2 of stainless steel screws, suitable for scenarios with limited budget but requiring rust prevention.
The contact area under force is large
The diameter of the disc head is larger (compared to round/flat heads), which disperses pressure and prevents the screw head from getting stuck in soft materials such as plastic and wood fiberboard.
