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.

Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.

Tek screws, named after their inventor Tek Screw Corporation, are designed with a unique thread pattern that allows them to tap their own hole in metal, wood, or composite materials. Their primary advantage lies in their ability to provide a secure hold without pre-drilling, saving time and effort on job sites. The 20-inch variant is particularly valuable due to its length, which enables it to penetrate deeper and handle heavier loads compared to shorter screws.
