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.

Buy the suit. Be sure to measure!
Size: Large, Color: Red, Size: Large, Color: Red
Suit looks better than the photo in person. The suit is also made well. Great fabric and pattern! My son is 6'1 and weighs around 135-140 pounds. I ordered a size large for him so the pants would be long enough. The pants were a little big but it was nothing a belt could not fix. The jacket and vest fit well too. The item also arrived on time. ***Suit runs small BUT if you take out time to do the measurements you will get the correct size.***

Fits like a glove, looks like a million!
Size: Small, Color: Purple
Bought this as a gift for him and very impressed. Looks like a million dollars, fit true to size, looks tailored not cheap. Fabric is quality, stitching is done well and the pants have a nice hidden elastic extender that helps if he goes up or down a few pounds. Very impressed!

It was the perfect suit for our big day!
Size: X-Small, Color: Purple, Size: X-Small, Color: Purple
Purple size xs. He's 5'9" 145-150lbs. Very impressed with this suit. The color and pattern is awesome. The fit was good. I would say this suit runs large. Usually he wears a Medium in everything but ordered an XS and it fit very well. The pants were long we had to get those hemmed. There was a few stray strings by the end of the night in areas of the suit. But overall good quality. And for a great price.
