Lug Nuts
Trailer wheel lug nuts in multiple sizes and finishes for replacement, upgrade, or marine applications. Available in standard zinc-coated steel for everyday trailer use, and premium stainless steel for boat trailers, coastal environments, and any application exposed to salt water or corrosive conditions.
Choose from coned seat, flange seat, acorn, and 2-piece swivel flange styles in 1/2"-20, 9/16"-18, and 5/8"-18 thread sizes. Open-end and enclosed (capped) versions are available, with multi-pack options for tandem and triple axle setups.
All Hydrastar lug nuts are designed to meet or exceed standard trailer wheel mounting requirements. Cone seat lug nuts work with standard trailer wheels, while flange seat options are required for some aluminum wheels. Always match your lug nut type to your wheel manufacturer specs.
