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.
