値以下では絶縁性を保持し、設定値に達すると絶
縁性を失つて、ボルト・ナツトと締付工具とを導
通させる被覆を形成したことを特徴とする締め過
ぎを防止できるボルト・ナツト。 Forming a coating on the bolt head or nut that maintains insulation when the tightening force applied is below a set value, loses insulation when the set value is reached, and provides electrical continuity between the bolt/nut and the tightening tool. Bolts and nuts that can prevent over-tightening.
