This is your go-to tool when creating new threads. Add machine screws to just about any material from metal to wood. Use it to form new threads, re-form burred threads or clean out plaster obstructions. Each tap size rethreads to next larger size if threads are stripped.

这是创建新线程时的工具。将机器螺钉添加到从金属到木材的材料。用它来形成新的线，重新形成毛刺线或清除灰泥障碍物。如果线程被剥离，则每个抽头大小重新线程到下一个更大的大小。
