トの防錆用保護キヤツプ。[Scope of Claim for Utility Model Registration] (1) In a bolt/nut formed by screwing nuts N ₁ , N ₂ onto threaded rod portions 5, 15 of a through bolt B ₁ or a stud bolt B ₂ , the nuts N ₁ ,
N ₂ and its nuts N ₁ , N ₂ form a nut side cap C ₁ that is attached to the threaded rod portions 5 and 15 exposed from N 2 , and the nut side cap C ₁ is attached to the nut N _{1 .} , a nut cover cylindrical portion 7 that covers the outer periphery of the _N2 .
and a screw cover cylindrical portion 9 in which a female thread 8 is carved to be screwed into the screw rod portions 5 and 15. (2) Attach a relatively thin head side cap C ₂ made of synthetic resin and filled with oil clay X or silicone rubber to the bolt head 4 of the through bolt B ₁ or threaded bolt B ₃ . A rust-proof protective cap characterized by molded support. (3) In a bolt/nut formed by screwing a hexagonal nut _N1 onto the threaded rim portion 5 of a through bolt _B1 , the hexagonal nut _N1 is crowned with the threaded rim portion ₅ exposed from the hexagonal nut N1. A nut side cap _C1 made of synthetic resin is formed, and the nut side cap C1 is made of synthetic resin.
₁ is composed of a relatively large-diameter nut cover cylindrical portion 7 that covers the outer circumference of the hexagonal nut _N1 , and a relatively small-diameter screw cover cylindrical portion 9 in which a female thread 8 is carved to be screwed into the threaded rod portion 5. The hexagonal head 4 of the through bolt B ₁ is crowned with a comparatively thin head side cap C ₂ made of synthetic resin filled with oil clay X and supported by molding. Features a rust-proof protective cap for through-bolts.
