自攻螺钉作为塑料制品的紧固件,广泛用于电视机,收录音机以及仪器仪表上。在装配过程中,由于塑料件底孔孔径偏小、孔深不足、拧入时对底孔歪斜太多等原因,自攻螺钉折断在塑料件底孔中是常有的事,而取出折断的螺钉往往很困难。解决方法:取一把电烙铁,通电后将烙铁头对准折断的自攻螺钉尾端加热片刻,待塑料件底孔受热涨大后,用镊子或尖嘴钳夹紧螺钉尾端即可轻轻 Self-tapping screws as fasteners for plastic products are widely used in television sets, tape recorders and instrumentation. In the assembly process, plastic parts due to the hole diameter of the bottom hole is too small, insufficient hole depth, screwed into the bottom hole too much skew and other reasons, self-tapping screws break in the plastic bottom hole is common, and remove the broken Screws are often difficult. Solution: Take a soldering iron, turn the tip of the soldering iron at the end of the self-tapping screw and heat it for a while. After the bottom hole of the plastic piece is heated up, clamp the end of the screw with tweezers or pointed nose pliers light
