貫通孔を経て被防食金属体の雌螺子穴へボルトを
螺合して、犠牲陽極を被防食金属体に一体的に固
定し、前記穴内全体に、ボルト頭部を被覆する如
く絶縁樹脂を充填するボルトの絶縁手段において
、前記穴中央部面を若干高く形成すると共に、穴
中央部面の直径を、ボルト頭部の最大径よりも小
さく形成したことを特徴とする犠牲陽極における
埋込み用固定ボルト穴構造。 The sacrificial anode is integrally fixed to the metal body by screwing a bolt through the bolt through hole in the center of the bolt hole in the center of the sacrificial anode and into the female threaded hole in the metal body to be protected. In the insulating means for the bolt, which is filled with insulating resin to cover the bolt head, the center surface of the hole is formed slightly higher, and the diameter of the center surface of the hole is smaller than the maximum diameter of the bolt head. A fixing bolt hole structure for embedding in a sacrificial anode, characterized by:
