FastenMaster FMHLGM412-50 HeadLOK Heavy-Duty Flathead Fastener, 4-1/2 Inches, 50-Count

Tougher than nails. Drive in fast and grip strong. Flat head is a good look and doesnt penetrate the wood like other legs. Each box has a driver as well. 5 stars

I was recommended to use these by a friend. After seeing the price, I was a little hesitant, but figured Id try a box out. Wow! I love these screws and they leave me feeling like my builds are secure and stable. Very nice head that allows for the screws to be driven in to wood without stripping the product. I also like the wide head, which allows me to pull my materials in tight without blowing through the lumber or splitting it. I strongly recommend these screws if youre building and want a secure joint.

robust, easy to fasten, should hold securely for a long time!

Much nicer looking than old-school lag bolts that tend to snap. Made installing a set of exterior steps much easier. Would purchase again

Great product. It is easier to use then most lags

I have used these screws when making raised garden beds. They work great, and I found the price here on Amazon cheaper than the local big box stores.

If you work on big boy projects, sometimes you need big boy parts, and these screws are the real deal. Bought my initial pack at Lowes as I was working on my deck.I went back when I ran out, and, of course, found out they were out of stock. When I turned to the clerk behind the Pro Service Desk for help, his reply (and I kid you not) was, Cant Help Ya Buddy and sat back down. And, big box stores wonder why people shop online. So, we ordered the screws online. They are made in the USA, and if you are needing to brace some 6 x 6 or other large deck lumber, these are going to save you time and money. I also use them on the ledger boards because they screw in flush to the board, and I can put my joist hangers over the screw if necessary. I like the fact they are thin, so they dont crack the boards, but have the strength of larger screws. And, I buy USA where I can.

Cheap material. I tried to screw it into a tree to hold something. I used the drill to open the first 5”, but it still strip the head. Used a good quality 5” screw that I had instead, and that worked fine. Perhaps you can use it for very soft wood.

Worked great!

These are EXCELLENT! Ive built my deck with them, well the support portions - all 2x12 and such. These can take the abuse of a 1/2 horse drill and hammer drill, and just pulls the boards together perfectly. Always going to be using these from now on!
