2" Split Lock Washer Hot Dipped Galvanized Plating

Regular Split Lock Washer with Hot-Dipped Galvanized Plating – Rugged Locking Performance for Harsh Outdoor Applications (Inch Sizes)

When durability and corrosion protection are top priorities, the Regular Split Lock Washer with Hot-Dipped Galvanized (HDG) Plating delivers exceptional performance in outdoor and heavy-duty environments. Designed for inch-sized fastener systems, this washer combines the mechanical reliability of a traditional split lock washer with the long-lasting rust resistance of HDG coating—making it ideal for structural and industrial use.

Crafted from low carbon or hardened steel, the split lock washer features a helical design that provides tension and friction when compressed between a nut and a substrate. This mechanical action helps resist loosening due to vibration, dynamic loads, or thermal cycling. The hot-dipped galvanized finish applies a thick, zinc-based protective layer, which offers superior corrosion resistance in moisture-heavy, coastal, or chemically exposed environments.

Engineered to match inch-based bolts and nuts, this washer is a trusted companion in construction, utility infrastructure, marine hardware, fencing, and outdoor equipment installations where fastening integrity must stand the test of time and weather.
