使用螺丝取出器。螺丝取出器是专门用来取出坏螺丝的工具。一般在五金店都能买到，而且价格也不贵。用螺丝取出器能让你省点劲。
要卸掉螺丝头磨花或者断掉了的螺丝，用螺丝取出器最方便了。WH.performance.mark(‘step1_rendered’);

在螺丝上钻个洞。选一个比螺丝更细一些的钻头，对准螺丝中央钻一个洞。如果钻不动，那就换一个小点的钻头试试，比如1.6毫米的钻头。钻的时候要轻一点、慢一点，以免弄断钻头。

用锤子把螺丝取出器锤到底。把螺丝取出器插进钻好的洞里，用力按紧。然后用锤子把它敲到底。[2]

逆时针转动螺丝取出器，把螺丝拧下来。把螺丝取出器使劲按进螺丝后，用螺丝刀或者手钻逆时针转动螺丝取出器。螺丝取出器上的螺纹会卡住螺丝，拧动螺丝取出器的时候，就可以把螺丝一起卸下来了。[3]

如果还是拧不下来，试试用力敲打螺丝取出器，让它在螺丝里插得更深一点；或者在螺丝上倒点润滑剂。然后等30分钟再试一试。

如果没有螺丝取出器，你也可以用钳子夹住螺丝杆，然后把螺丝拧下来。要把断头螺丝拧下来，可以用钳子夹住螺丝杆的末端把它拧下来。[4]

换其他尺寸的螺丝刀试试，看能不能拧动。有时候，即使螺丝头已经磨得很花了，换一个大一点或者小一点的螺丝刀，就可以卡住螺丝头。如果十字螺丝刀不行，你可以换个一字螺丝刀试试。[5]

如果第一次没有拧动，不妨换把其他尺寸的螺丝刀。如果硬拧，可能会让螺丝头变得更滑。

在螺丝头上放一块橡胶条，可以增加螺丝头和螺丝刀之间的摩擦力。把橡胶条切成长条状，这样放在螺丝头上时就会比较平，不会卷在一起。然后把橡胶条盖在螺丝头上面，再用螺丝刀拧螺丝头。橡胶条可以增大摩擦力，没准就能把螺丝拧下来了。[6]

在生锈的螺丝上倒一些化学制品，没准会有助于卸掉螺丝。有时，生锈的螺丝会和周围的材料粘在一起。在螺丝上喷点或者倒点类似于润滑剂、烤箱清洁剂等化学制品，或者是碳酸钠（可乐）甚至柠檬汁，然后等待10分钟再试试。你可能需要重复几次上面的步骤，有时甚至要等一天才能看到效果。[7]

如果螺丝头磨花了，拧的时候老是打滑，可以用胶水把螺丝刀或钻头和螺丝头粘在一起。在螺丝头上滴一些强力胶水，然后把螺丝刀或钻头粘在上面。等胶水干了之后，向下用力顶着螺丝刀或钻头，把螺丝拧下来。[8]

如果还是不行，可以试试用旋转切割器在螺丝上切一道新的凹槽。如果螺丝头已经彻底磨花了，你可以用旋转切割器在螺丝头上切一道新的凹槽。然后用一字螺丝刀或一字钻头把螺丝拧下来。[9]

要是螺丝实在是拧不下来，可以直接用钻头钻掉它们。如果上述方法都不奏效，那么就用钻头钻掉螺丝。例如，你可以用比螺丝大一号的钻头向下钻，直接把螺丝钻没。你也可以用钻头把螺丝头钻掉，然后用钳子把螺丝杆拔出来。[10]
