A rugged, architectural accent for outdoor builds
The cool, galvanized sheen introduces a subtle industrial note that pairs beautifully with natural woods. I love the domed head—its minimal profile reads polished while staying purposefully utilitarian. Use these along a cedar fence or deck fascia to create a rhythmic, intentional detail. Durable and refined, they’re the quiet luxury hardware your exterior deserves.
