The screw angle of the auxiliary thread and the screw angle of the main thread are not Similarly, the spacing of the helical threads of the auxiliary threads is also different from the spacing of the helical threads of the primary threads. That is, a broken tooth gap is provided on the thread of the main thread at the intersection of the main thread and the auxiliary thread.

已知公告第M410118號「具緊迫鎖合效果之木螺絲」，其技術特徵係在於：螺桿上設有擴孔區，該擴孔區內之任兩螺牙間的桿體上凸設有傾斜的肋塊，且該相鄰之任兩肋塊端緣緊抵於同一螺牙上。亦即擴孔區內之兩螺牙間設置傾斜凸出的肋塊，且上下相鄰之兩肋塊端緣緊抵於同一螺牙上。此創作之傾斜凸出肋塊雖具有擴孔作用，但各傾斜凸出之上下肋塊呈非同向連續設置，也就是呈現出一段肋塊為順向傾斜凸出，相鄰的另一段肋塊為反向傾斜凸出。It is known that the bulletin No. M410118 "wood screws with tight locking effect" is characterized in that: the screw is provided with a reaming area, and the shaft between any two screws in the reaming area is convexly inclined The ribs, and the edges of any two adjacent ribs abut against the same thread. That is, the ribs are inclined and protruded between the two threads in the reaming area, and the end edges of the two ribs adjacent to each other are tightly pressed against the same screw.
