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.


Choose this 50-pack of galvanized carriage bolts for reliable, clean-looking fastening on your next deck, fence, or outdoor build.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls

Soild

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.
