THESE ARE VERY HIGH QUALITY SCREWS FROM A TRUSTED SELLER
These screws exceeded my expectations. They are incredible strong and I experienced not one failure after screwing down 200. They were able to tightly pull down 4x6 lumber on a small bridge construction. This was surprising since some of the beams were slightly warped. I will be buying from Jake Sales again!! Thanks

I have used many different sizes of this screw, and you get what you pay for. My go to construction screw.

10/10 quality
Most solid screws I've ever come across, I'm building a heavy timber 14 ft tall porch 1200 square foot porch. Occasionally I have stripped a few of the star bit heads but that is mostly my fault. Otherwise, you won't be disappointed. Certainly these are better than what I've purchased from Lowe's and home Depot

Super long screw.... works good for it's intended use.
What can I say... it's a super long screw. I use them when I need to lag into beams... through a foam insulated roof. T30 head drives in nice with an impact driver without stripping out.

T40 bit not included
These work really good overall. They are a little slow to bite but once they do they go. I didn’t pay attention to the bit size needed but luckily enough I had one. It would be nice if they included one in the box. A good value compared to big box stores.

Great screws!
These are great screws, the T 40 Torx head works very well, doesn’t strip out like the T 30 or 25’s sold by other vendors

Jake sales takes pride in their business.
Nothing to dislike... Just that these 7" lag screws are exactly what I ordered. Nothing substituted. Quality great, made of quality material and whatever is built with these lags will never ever come apart.. Great product Jake Sales.

Don't lag behind..
These lag screws work great when building a deck. My deck wouldn't look as beautiful without them. I strongly suggest you drill a hole before hand. These go right in with out issue.
