PROBLEM TO BE SOLVED: To provide fasteners that disperse electrical energy.SOLUTION: An apparatus includes a fastener. The fastener includes a head, a cylindrical shank 440 that extends from the head and is dimensioned to fit and engage a corresponding hole, the cylindrical shank having a surface 520, and a coating 510 that is discontinuously speckled around a circumference of the surface 520 and extends axially along the shank 440, the coating 510 leaving irregular portions of the surface 520 of the shank exposed. The coating exhibits a higher lubricity than the surface, and the coating exhibits a higher withstand voltage than the surface.SELECTED DRAWING: Figure 5 【課題】電気エネルギーを分散させるファスナを提供する。【解決手段】ファスナであって、ヘッド部と、ヘッド部から延在し、かつ、対応する穴に嵌まって係合するよう寸法決定されている、円筒形のシャンクであって、表面５２０を有する、円筒形のシャンク４４０と、表面５２０の外周の周りで不連続にまだら模様にされ、かつ、シャンク４４０の軸方向に沿って延在するコーティング５１０であって、シャンクの前記表面５２０の不規則な部分が露出したままとなる、コーティング５１０とを備える、ファスナを備える、装置であって、コーティングが表面よりも高い潤滑性を示し、コーティングが表面よりも高い耐電圧を示す、装置。【選択図】図５
