Stainless Steel Self Tapping Screws

Stainless Steel Self Tapping Screws do not need to be used with nuts because their threads are self-tapping. The design of the tip of the tail enables it to form internal threads in the hole through extrusion when it is screwed into the hole on the plastic metal material and form a reliable locking thread connection. Its structure makes it easy to use and only requires a screwdriver to complete the fixing work. At the same time, due to the self-tapping performance and special pan head design, it can be firmly fixed in the wood, providing a stable connection effect and not easy to loosen.

This self-tapping screw main rod is provided with a pan head at the top and a pointed cone at the bottom. The outer wall of the pointed cone is provided with fine thread, and the outer wall of the main rod is provided with anti-stripping reverse thread and positive thread. These designs can prevent the main rod of the self-tapping screw from reversing under vibration, thereby improving the stability of the connection and fixation. Cross pan head self-tapping screws can be made of carbon steel or stainless steel. Common specifications include screws of different sizes such as M3, M3.5, and M4.
