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.

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly. Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration. Ended up running self tapping screws thru parts to complete assembly.
