A Clean, Classic Fastener for Timeless Outdoor Builds
The gentle dome of the carriage head delivers a refined, unobtrusive look that keeps surfaces visually calm. I love how the square neck disappears into the timber, leaving a tidy, architectural finish. Use them to detail a garden gate or bench where hardware should feel intentional, not loud. Durable galvanization makes them a quiet luxury essential for outdoor structures that age gracefully.
