Hot-Dip Galvanized Anti-Rust Split Lock Washers
Our hot-dip galvanized split lock washers carry a heavy zinc coating that delivers anti-rust and corrosion protection for long-term outdoor and humid-environment service. Manufactured to ASME B18.21.1 from high-grade spring steel, each split ring keeps its spring tension and prevents loosening under vibration, making it a reliable choice for structural, industrial and heavy-duty bolting.
