Frequently Asked Questions (FAQ):

Q: What size drill bit should I use for these 5/16 in. carriage bolts?
A: Use a 5/16 in. hole for the shank; in wood, slightly undersize may improve neck bite. For metal, match 5/16 in. and deburr.


Q: Are these suitable for outdoor use?
A: Yes. The hot-dipped galvanized finish provides excellent rust protection for exterior projects like decks and fences.


Q: Do I need a washer with the round head?
A: Typically no; the broad round head provides a semi-flush finish. Use a nut and optional washer under the nut if desired.


Q: What nut and thread type pairs with these bolts?
A: These use coarse SAE threads; pair with matching 5/16 in. coarse-thread nuts.


Q: Can they be used in treated lumber?
A: Hot-dipped galvanized fasteners are appropriate for most pressure-treated lumber; always follow local code and lumber manufacturer guidance.

Good quality and design, but...
Size: Medium, Color: Black(windmill)
The design, fit, and feel are nice, and I'm glad I used the sizing chart within the pictures because typically I have to buy a large in other brands. However, the collar is unsupported and the fabric is like others have said (thin, silky, a little like a shower curtain, and a little like a disco shirt, though surprisingly not stretchy). Not necessarily bad, just unexpected, and pleasantly light. I bought the white polka dot and the gray diamond print. The white was a tiny bit see through and the gray has a very subtle color change throughout the fabric undulating slightly lighter to slightly darker, which I did not notice from the pictures, but was nice. Unfortunately, the pocket fabric didn't switch lightness and darkness the same as the rest of the shirt, so the one I received had a dark splotch right next to the lighter pocket fabric making it look like a grease stain on the center of the shirt. The two were also slightly different in size even though they were both listed as the same size (medium). The white one pulled across the chest and had more fabric on the sides, the grey one fit beautifully with a nice taper, but it had the "stain." I did not wash mine or try to get the wrinkles out, but the crease of the fabric upon arrival is very prominent, and I would imagine it is hard to get out. All-in-all, I didn't love the shirts, so I returned them. But the fabric was nice, thin, and comfortable but I wouldn't say cheap. The shirt was a little more casual with the unsupported collar which is just good to consider. And there were some minor inconsistencies with sizing. I would have kept the gray had the pattern lined up better and perhaps I just got the one bad one.

I love these shirts!
Size: 4X-Large, Color: Blue Combo
These shirts are great! They’re super comfortable, super stylish, and they fit me! I’m a fat guy and they make me look great. Here’s a tip if you’re fat like me. Sit down in a chair and measure around your biggest area, then use that as your “chest” size on their charts. Order whatever size is just a little bigger than your measurement. Always check the charts because they’re not always the same.
