A Sleek, Industrial Anchor for Wood-to-Metal Harmony

The streamlined dome head and crisp zinc sheen bring a refined industrial touch to utility builds. I love the self-locking square neck—it tucks elegantly behind the surface, allowing the face material to remain visually uninterrupted. Use these in exposed joinery for workbenches or shelving where form meets function. A polished essential that elevates everyday construction to luxe craftsmanship.

The only toy my dogs can’t destroy and love
Color: Onyx Black - Most Durable
I am thrilled to have found one toy my dogs don’t destroy immediately. They have torn up Fenrir hammers, the black kongs of all sizes, the monster k9 stick, nylabones, and they don’t like the goughnut at all (it stinks like a bad tire). This is the first one they both love and haven’t been able to destroy immediately. It does allow little tooth marks, but that’s what makes it fun for them. They are very happy playing with it and I’d say this one was worth every dollar. Update Months Later: We’ve gone through 2/3 now. I got two initially, and one has lasted long term. They still haven’t completely destroyed it. They did destroy a second one quickly so I suspect a flaw in it. They sent me a new one and they took a while, but they did destroy the third to the point we had to throw it away. Despite that, one still remains and our dogs still love it. It’s still the best for the money compared to others. We have two Bully XL’s that are each close to 100 pounds.

Indestructible
Color: Onyx Black - Most Durable
This is actually indestrutible! Be careful though, it's wicked hard/heavy. It isn't a ball you want banging into things. Use outside!!

Not indestructible, but the best I’ve found
Color: Onyx Black - Most Durable, Color: Onyx Black - Most Durable
This thing is unexpectedly heavy for its size. My 18 month old Giant Schnauzer is obsessed with fetch but destroys every ball she gets. The other brands marketed for extreme chewers tend to last about a day or two before they’re totally shredded. She’s had this one for about 2 weeks and it’s looking rough, but still holding together for the most part. I appreciate that as it comes apart it does so in little pieces rather than large chunks. While it’s far from indestructible, it’s the strongest I’ve found so far.
