Are pole line fasteners always galvanized?

Due to the exposure to outside elements, pole line hardware is required to be hot-dip galvanized. All pole line hardware has this requirement, not just the fasteners. When galvanizing bolts, it is critical that the bolts be galvanized in a system set up specifically for threaded fasteners to ensure clean threads for a proper thread fit. Pole line fasteners are galvanized per ASTMF2329 and ASTM A153.
