Questions & Answers

Is the description for the 3 - stainless steel? I see that the 1/8 size is for the 4in size, but it's the 3-inch size that I'm looking for. Stainless steel of 1/8 inch thickness?

The 5/16 x 3-inch bolt isn't the one you're looking for. The structural screws in the size of 1/8 inch are not stainless steel.

Are these intended to be used with pressure-treated lumber?

Using lag bolts is less convenient
5/5

These were purchased to be used in the construction of a wooden swing set's components. They're known as the "cats meow!" group. " It's a lot easier and cleaner than lags. " The grip strength is incredible! Which is something I would have done sooner if I had known about them.

THIS IS WHERE HANDMADE BEGINS
5/5

Great screws for the structure. I'm not going to use any other screws from now on. Period. Even if you don't care about structure.

Good Value
5/5

Good value for the same items you'd find at Home Depot, and it saves you gas by not having to drive there.

It's incredible
5/5

I used a variety of types, and this is one of them. WOW, this is incredible. I tried a few and this one is by far the best. The head is large enough to prevent the wood from being crushed. The tip is well-designed to sink in without exerting too much force. When you only have one hand, that's a significant amount of money; MUST BUY!.

For long-term fence repair, this is the best option
5/5

Other screws we've used rusted or didn't hold up as well as these. This is exactly what we were looking for.
