If you’re in the manufacturing industry and you have products with plastic parts, then finding the right screws that can cut through plastic can be a challenge. Thread-cutting screws come in different materials, sizes, and thread types. But, with the right knowledge, you can easily find the best screws that will make your products more durable and secure. In this blog post, we will guide you on how to find the right thread-cutting screws for plastic.
Material
The first thing to consider when looking for thread-cutting screws for plastic is the material. The best materials for these screws are zinc and stainless steel. Zinc screws have a high resistance to corrosion and are perfect for plastic materials that are not exposed to harsh environments. On the other hand, stainless steel screws have excellent corrosion resistance and are ideal for products that will be subjected to harsh outdoor conditions.
Size
Size is also an important factor to consider when selecting the right self-thread-cutting bolts. The size of the screw depends on the thickness of the plastic. Thinner plastics require smaller screws, while thicker ones need larger screws.
Thread Type
The type of thread is another crucial factor to consider when searching for thread-cutting screws for plastic. There are three types of threads that are commonly used in plastic, which are self-tapping, machine, and thread-forming. For soft plastics, self-tapping threads are recommended because they create their own threads without causing damage to the material. Machine threads, on the other hand, are suitable for hard plastics because they require pre-drilled holes.
