Self tapping screws are a type of screw with self-forming threads, which means they can tap their own holes without the need for pre-drilling. Unlike regular screws, self tapping screws can penetrate materials without the use of nuts, making them ideal for various applications. In this article, we will focus on two types of self tapping screws: A-thread and B-thread, and explain how to differentiate between them.
A-thread: A-thread self tapping screws are designed with a pointed tail and larger thread spacing. These stainless steel screws are commonly used for drilling or nesting holes in thin metal plates, resin impregnated plywood, and material combinations. The unique thread pattern provides excellent grip and stability when securing materials together.
B-thread: B-thread self tapping screws have a flat tail and smaller thread spacing. These stainless steel screws are suitable for lightweight or heavy-duty sheet metal, colored casting plastic, resin impregnated plywood, material combinations, and other materials. The smaller thread spacing allows for a tighter grip and prevents slippage in softer materials.
Differentiating A-thread and B-thread: When it comes to distinguishing between A-thread and B-thread self tapping screws, you can consider the following factors:
Thread pattern: A-thread has larger thread spacing, whereas B-thread has smaller thread spacing.
Tail shape: A-thread has a pointed tail, while B-thread has a flat tail.
Intended applications: A-thread is commonly used for thin metal plates and resin impregnated plywood, while B-thread is suitable for sheet metal, plastic, and other heavier materials.
In summary, self tapping screws are a versatile fastening option that eliminates the need for pre-drilled holes and nuts.
