- ナットの雌ねじのねじ溝に被覆されためっき金属のうち、ねじの谷底に残った余分な金属を切削するようにした溶融めっき処理ねじ溝の仕上げ具において、
軸部には先端側から後端側に向けて位置決め部、切刃のないガイド部及び切刃のある切削刃部が形成され、
上記切削刃部はナットの雌ねじのめっき処理後のねじ溝と嵌まり合う複数条の完全ねじ山形状の部分を有し、該完全ねじ山形状の部分には上記軸部の回転によって上記ねじ溝に被覆されためっき金属の余分な部分を切削するねじ山形状の切刃が形成され、該完全ねじ山形状の部分の前方に上記完全ねじ山形状の部分のねじ山頂部を切除した複数条の断面台形状の部分を有し、該断面台形状の部分には断面台形状の切刃が形成され、上記切削刃部の複数条の断面台形状の部分は上記ガイド部の断面台形状の部分から上記切削刃部の完全ねじ山形状の部分に向けて高さが漸増するような高さとなっており、上記切刃の回転方向の手前に切削しためっき金属を受ける凹部が形成され、
上記ガイド部は上記完全ねじ山形状の部分のねじ山頂部を切除した断面台形状をなし、ナットの雌ねじのめっき処理後のねじ溝と嵌まり合い、ねじ山フランクと摺接することによって上記切削刃部を案内し、
上記位置決め部は軸線方向に少なくともねじ山2条以上の長さで、ナットの雌ねじのめっき処理後のねじ山頂部と摺接する外径の円柱形状をなし、該円柱形状の先端部分はテーパー面状をなし、上記軸部の中心軸線をナットの中心軸線と一致させるように上記軸部を位置決めするようになっていることを特徴とする溶融めっき処理ねじ溝の仕上げ具。
