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.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
