Frequently Asked Questions (FAQ):

Q: What size are these carriage bolts?
A: They are 3/8 in. diameter by 1 in. length with coarse (SAE) threads.


Q: What material and grade are they?
A: They are made from Grade 2 steel with a zinc-plated finish.


Q: Are these suitable for outdoor use?
A: The zinc plating offers light corrosion resistance, making them fine for indoor and some sheltered outdoor applications; for harsh or coastal environments, consider stainless or hot-dipped galvanized hardware.


Q: Do these include nuts and washers?
A: No. This box includes 100 carriage bolts only; nuts and washers are sold separately.


Q: How do carriage bolts stay from spinning?
A: A square section beneath the domed head embeds into the wood, locking the bolt in place as the nut is tightened.


A Clean, Polished Fastener for Seamless Woodwork

The domed head lends a subtle, tailored finish that feels intentional rather than utilitarian. I love how the square neck tucks into timber, keeping the face pristine without extra hardware clutter. Pair these with oiled oak or painted millwork for a crisp, modern-meets-classic detail. A small choice that elevates craft—and the hallmark of refined, livable luxury.

It’s half the size of the last one that I purchased. It’s hard to tell from the pictures sometimes.
Should always check the dimensions of items because the pictures can mislead you sometimes The bonus is a great product. It lasts a long time and it doesn’t break. I give this product five stars excellent but the size I purchased is for a smaller dog. Best Bone is what Wakanda growled. Thanks everybody 🚀🇺🇸

Holds up really well under an extreme chewer
Size: Dumbbell
My dog is only 18 lbs , he can chew through anything. This little not so little chew toy has held up really well and keeps him occupied... although the blue rubbery part does break off in little tiny pieces it is not breaking off in big chunks, it has lasted more than 2 months at this point. He has been able to put some dents and dings in the plastic Center, but again considering he destroys everything in a matter of moments I'm very pleased with this. Quality is good, and he likes to carry it around the house... also found out if he turns it it makes a funny little noise which keeps them entertained. Perfect size for my dogs. The wait is Hefty enough that he knows he's carrying it but not so big and weighted that he doesn't enjoy it.

Won’t buy again
Size: Tripod, Size: Tripod
It started out great. But then it came apart and my puppy almost swallowed the piece that makes noise. Otherwise, it’s been a good brand of bones. Just not this particular one. The end unscrews and came apart. Not great!
