Screw mount correction

Since the bolt became stiff at the bottom of the thread mount, I bought it for correction, but since the tip of the tap is very pointy despite # 3 (upper), I can not get in to the bottom, so tap the tip I modified a screw thread by scraping a few.. As I am # 3 for finishing, I do not think it is necessary to sharpen ahead.

In the general tool shop, it is quite a lot that there are many unify screws not available, this time very much.
