Frequently Asked Questions (FAQ):

Q: What tools do I need to install these carriage bolts?
A: Use a drill to create a pilot hole and a wrench or socket for the nut; the square neck locks into the wood so a driver on the head is not required.


Q: Are these bolts suitable for outdoor use?
A: The zinc plating offers basic rust resistance; for harsh outdoor environments, consider hot-dipped galvanized or stainless steel options.


Q: What thread type do these bolts use?
A: They feature coarse threads compatible with standard SAE nuts and washers.


Q: Do I need washers under the head?
A: Typically no—the round head provides a semi-flush finish, though washers can be used under the nut if desired.


Q: What size are these bolts?
A: Each bolt is 3/8 inch diameter and 2-1/2 inches long.

35% cotton shirt, 25% linen suit
Color: White, Size: 6, Color: White, Size: 6
This formal suit is not as white as I thought it was going to be. It’s off white due to it having 25% linen, which gives it a natural, “more expensive” sort of look. My 5yo said “it’s a little itchy but looks nice”. I think it’s just stiff because it’s new. I’m going to wash the button shirt and see how it is after washing. I do wish it was 100% cotton. The button shirt is made of a cotton blend with 35% cotton. The stitching is very clean. Well made. As you can tell, it’s a little loose on my average size 5yo. I got him size 6. This will be a great suit for one of the kids piano recitals.
