At this time, the arc formed by the cutting angle 141 is at least one-third of the radius of the thread 14, that is, the thread 14 When the radius is 3 mm (mm), the circumference of the cut corner 141 is 3/3=1R or more; therefore, when locking, the drill lock 13 is pressed against the object (not shown in the figure) by locking A closing tool (not shown in the figure) links the screw head 11 to drive the cutting angle 141 of the screw teeth 14 to cut the object, so that the screw 1 is screwed into the object.

However, after actual use, it was found that during the locking process of the conventional screw 1, in view of the fact that the cutting angle 141 is designed in an arc shape, the connecting surface 142 connected between the any two cutting angles 141 is also circular The arrangement of the cutting corners 141 makes it difficult for the cutting process of the cutting angles 141 to be effectively cut, and at the same time makes the coupling surface 142 rub against the object during the cutting process, and there is no more redundancy between the cutting angles 141 and the coupling surface 142 There is space for chips. In addition to increasing the locking resistance of the screw 1, the cutting speed becomes slower, so that the object cannot withstand excessive torque and cracking occurs, so it can not only effectively achieve fast locking, which will affect the screw 1. The locking positioning still needs to be improved.

Of course, the first axis can be arranged in a concentric extension with respect to the longitudinal axis. At the same time, an imaginary line extends through the arc-cutting portion based on the longitudinal axis, and extends through the two contacts based on the longitudinal axis. Two boundary lines, an angle between 20 degrees and 25 degrees is formed between each boundary line and the imaginary line, so that the angle formed between the two boundary lines does not exceed 50 degrees, so that the The arc formed by the arc-cutting part is set not to exceed one-quarter of the maximum screw radius, which is beneficial to the cutting of the fastener in a sharp and rapid manner when locking, which greatly reduces the locking of such teeth During the process, friction occurs with the locked objects to reduce the locking torque, effectively improve the cutting ability of the fastener and increase the locking speed, so that the screw has extra space for chip storage, and it can also avoid the formation of chip accumulation The cracking of the material happened.
