A Clean, Classic Fastener for Crafted Woodwork

The domed silhouette and zinc sheen bring a refined, utilitarian elegance to cabinetry, benches, and custom storage. I love the square-neck detail—it bites into wood for a smooth, unbroken face that feels tailored. Pair with pale oak and matte black brackets for a modern workshop aesthetic. Essential hardware that quietly elevates everyday builds to luxe, thoughtful design.

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

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.
