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.

Terrible white cast
Size: 1.7 Fl Oz (Pack of 1)
You will look like you just got blasted by Jack Frost in the middle of the summer. This sunscreen could double as a hair identifier from the way it clings to each strand, leaving an incredibly noticeable white residue. I am very fair and on my skin itself the white cast is much less obvious/fades, my eyebrows on the other hand? Frostbitten. Snow swept. Bringing to mind polar bears and penguins. It's an alright sunscreen. Does the job. Does not look good while doing it.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy. I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin. It feels comfortable for daily use and gives good protection without causing extra breakouts for me.
