Engine/Cutting tool/633301-633304 THREAD RESTORER

A square bar type restorer with 8 different lands.  Where a die cannot be used, a few easy passes with the appropriate land of the restorer over the damaged face of a bolt or a pipe will restore the thread without reducing the diameter.  As only the displaced metal is removed, the original fit is preserved.

一种方形杆式修复器，有8种不同的接地板。在不能使用模具的情况下，在螺栓或管道的破损面上用修复器的适当地面进行几次简单的穿孔，就可以在不减小直径的情况下修复螺纹。由于只移除了移位的金属，因此保留了原来的配合。
