self threading metal screws

The designation 1% 4% 2014 typically reflects specific characteristics associated with the screw's design and material composition, indicating its strength and suitability for particular applications. In many cases, the numbers denote the alloying elements in the screw's material, particularly in the context of steel to enhance corrosion resistance and overall durability. For instance, 1% might refer to the percentage of a certain alloy, while 4% could represent a different additive, both contributing to the screw's ability to withstand environmental stresses.

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.
