The use of stainless steel in self-tapping screws for plastic applications brings numerous benefits. Firstly, the hardness of stainless steel ensures a clean and precise thread, minimizing the risk of plastic damage during installation. This is critical, as excessive force or improper threading can lead to cracks or deformation in plastic components. Secondly, the corrosion-resistant nature of stainless steel safeguards the integrity of the screw, even in damp or chemically aggressive settings, ensuring a long-lasting bond. Lastly, the relatively low thermal expansion coefficient of stainless steel compared to plastic helps maintain a stable connection over time, preventing loosening due to temperature changes.
