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.

Fantastic and elegant looking nightstand or bathroom tray
Color: White 1 Pack, Size: 8" x 8" x 1.8"
I absolutely love this nightstand tray! The elegant gold trim gives it a luxurious look that instantly elevates my nightstand decor. It works perfectly as a perfume or cologne organizer and keeps all my bottles beautifully displayed. I’ve also used one as a dresser organizer countertop to hold jewelry and skincare, and another as a stylish key tray or key holder bowl by the front door. The quality is excellent and the design is both functional and beautiful. I love it so much, I’ll definitely be buying a few more to stack it up in a couple of my rooms. Highly recommend!
