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.

Very nice shirt -Good Quality
Size: XX-Large, Color: Red (Retro Rose)
My husband is 6'1, weighs 178 pounds and normally wears a medium or large. Just for reference his pant size is a 32-34 depending on the brand. We ordered a large due to the fact the shirt appeared to be fitted more at the waist and from looking at the description I knew it would not have much stretch due to the satin type material. I was right. The large fit perfect and hung well. My husband use to be very large in shoulders and arms, but with age he has lost muscle mass, and recently lost a lot in his belly, so usually mediums fit perfect now. But when he put his large on, a medium would not have fit good to be comfortable & give proper fit in stomach area, so glad we went with the large. The shirt was purchased to go on a Virgin Cruise for Scarlett night, and he plans to wear black pants with it as in the picture the company posted, and this shirt will be perfect for that. It is a nice shirt, good quality, and if someone wanted it for an event/cruise or just for a night to dress up, especially for a Caribbean/Spanish or Latin dance theme, this shirt is a perfect look to me. Buy it, you will not be disappointed. He has not worn it yet, not washed it, but I would not put in it with other colors, may fade a little like reds do, and definitely, only dry on low/delicate. May need a pressing/steaming, but overall, it was not horribly wrinkled when we received it. A toss in the dryer may just do the trick. Was delivered on time as it said it would. Hope this info helps you.
