Frequently Asked Questions (FAQ):

Q: What nuts and washers fit these bolts?
A: Use 5/16 in. coarse-thread nuts and corresponding flat or lock washers for proper fit.


Q: Are these suitable for outdoor use?

Q: Do these bolts have full threads?
A: Yes, they are fully threaded along the 5-1/2 in. length.


Q: What tools are needed for installation?
A: Tighten with a wrench or socket on the nut side; the square neck seats into wood to hold the bolt head in place without a screwdriver.


Q: Can they be used with metal?

Best skincare product ever
Size: 3.38 Fl Oz (Pack of 1)
This ampoule is THE BEST THING EVER. I’ve been in the skincare industry since 1996 and I’ve never used a product that works as well as this. I have sensitive oily skin and it has a lot of redness. After the first use the redness was completely gone and the hydration was noticeable. Do not pass on this stuff! Highly recommend it for anyone wanting immediate hydration. It’s thin and isn’t sticky or tacky. It feels like I don’t have anything on my face but the benefits are definitely noticeable.

Good product, but requires consistent use
Size: 1.85 Fl Oz (Pack of 1), Size: 1.85 Fl Oz (Pack of 1)
I’ve been using this centella ampoule for a while now, and overall I like it. The texture is lightweight, absorbs quickly, and leaves the skin feeling hydrated and soothed. It’s especially nice for sensitive or irritated skin. However, one important thing to note is that the results are not immediate. In my experience, you start seeing improvements with consistent, long-term use rather than overnight. If you’re patient and use it daily, it can definitely help improve your skin’s appearance. Overall, it’s a good product, but it requires consistency to see full results.

Keeping this in my skincare regimen for the long-haul
Size: 3.38 Fl Oz (Pack of 1)
No matter what skin type you are, you should have this in your lineup. I have larger pores - so sebaceous filaments & clogging. On top of the oiliness of my skin, I have more oily hair as well. But, I get dry patches like crazy. So it’s not easy to find products that meet all of my needs or are universal - it’s usually an “either or” situation. & I end up buying things for my drier days as well as products for my oily days instead of just one set of products. This is one that work well no matter what. There’s more than you’d expect based on the photos - the bottle is bigger. A little goes a long way. It’s very gentle. Great for barrier repair. Great for redness/irritation. A little goes a long way, but it can also be used more than once without being overwhelming. It’s great as a base for other serums/moisturizers, morning or night. It feels really good - clean & light (but not “light” as in ineffective, it still pulls its weight). Must have for anyone looking for trendy Korean glass-skin skincare - she’s one that will get you there without needing to invest in random “viral” products.

LOVEE (combo & oily skin) 🥹
Size: 3.38 Fl Oz (Pack of 1)
Pretty good! I loveee the applicator since it makes it really easy to apply. My skin has been super glowy ever since I’ve used this. Consistency is super thin and lightweight. My skin doesn’t exactly feel soft but looks really smooth. Despite it being this way, it hydrates super well!

My Go-To Toner After Trying Many Others
Scent: Unscented, Size: 12 Fl Oz (Pack of 1)
I’ve tried many toners over the years, including higher-end brands, and this one continues to stand out for both performance and price. It does exactly what I need without unnecessary extras. The formula feels gentle and effective, and I really appreciate that it’s alcohol free and fragrance free. Those two things are especially important to me, and this has been the only toner I’ve felt comfortable using during pregnancy. It doesn’t irritate my skin and fits easily into my daily routine. Despite the affordable price, it performs just as well—if not better—than many more expensive options I’ve used in the past. My skin feels clean and refreshed after using it, without any tightness or residue. Overall, this is a reliable, no-nonsense toner that delivers great results at a very reasonable price. If you’re looking for a simple, fragrance-free option that works well without breaking the bank, this is an easy recommendation.
