ボルトの防食用金具。[Claims for Utility Model Registration] 1. An anti-corrosion fitting 2 made of a low-potential metal with a greater ionization tendency than iron and capable of being fitted externally on the non-threaded portion side of the bolt body 1. A corrosion-proofing bolt characterized in that the corrosion-proofing metal fitting 2 is externally fitted on the non-threaded part side and is in contact with the metal surface of the bolt body 1 so as to be in electrical continuity with the bolt body 1. 2. It is made of a low-potential metal that has a greater tendency to ionize than iron, and is formed so that it can be fitted externally to the non-threaded part side of the bolt body 1, and when it is externally fitted, the bolt body 1
An anti-corrosion fitting 2 is formed with an inner diameter set such that the paint applied on the bolt can be peeled off, and the anti-corrosion fitting 2 is press-fitted onto the non-threaded portion side of the bolt body 1 so that the anti-corrosion fitting 2 can peel off the paint. An anti-corrosion bolt characterized in that it comes into contact with a metal surface of a bolt body 1 that has been coated. 3 The bolt body 1 is made of a low-potential metal that has a greater ionization tendency than iron, and the bolt body 1
An anti-corrosion bolt characterized by comprising an anti-corrosion metal fitting 2 which is formed to be able to be fitted externally onto the non-threaded part side of the metal fitting 2 and which is configured to bring the bolt main body 1 into an electrically conductive state when the metal fitting 2 is fitted externally. 4. The anti-corrosion bolt according to claim 1, wherein the low potential metal is zinc or a zinc alloy. 5. The anti-corrosion bolt according to claim 1, wherein the bolt body 1 has a substantially U-shape. 6. The anti-corrosion fitting 2, which is made of a low-potential metal with a higher ionization tendency than iron and is formed so as to be able to be fitted onto the non-threaded portion of the bolt body 1, is electrically connected to the bolt body 1 when it is fitted externally. An anti-corrosion bolt characterized in that the bolt body 1 is provided with an exposed non-painted part. 7. An anti-corrosion fitting made of a low-potential metal with a greater tendency to ionize than iron, and formed in a shape that can be fitted onto the threaded portion of a bolt. 8. A corrosion-proofing metal fitting characterized in that it is made of a low-potential metal that has a greater tendency to ionize than iron, and is formed in a shape that can be fitted onto the non-threaded portion of a bolt. 9.
