The Hot-dip Galvanized A325M bolt is a metric high-strength heavy hex structural bolt specifically engineered for steel-to-steel connections. Its defining feature is the combination of robust mechanical performance (tensile strength of 830 MPa) and superior corrosion resistance provided by the hot-dip galvanizing process. Unlike the ultra-high-strength A490M bolts, A325M is less susceptible to hydrogen embrittlement, making it the preferred fastener for bridges, highway infrastructure, and outdoor steel frames where long-term durability in harsh environments is essential.
