This is a custom-designed drywall screw with a unique thread structure. The lower half of the thread features a standard right-hand thread, while the thread near the screw head is reverse threaded. This design allows the screw to quickly penetrate drywall, and the reverse thread section locks the material securely in place, preventing loosening and board bulging. It is mostly used for connecting wood studs and drywall, offering stronger holding performance than regular drywall screws.
The screw is made from C1022A low carbon steel and goes through a heat treatment process, giving it high hardness and durability.
This type of bugle head self drilling screw provides enhanced anti-loosening performance during vibration or movement.
