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

Drives like a champ. Way easier and faster than the 3/8 bolt it replaces. Hoping the engineers did their homework because these fasteners are too good to believe.

This fastener is easy to use and for the most part seemed to do the job. However, I needed 48 fasterners to accomplish my project. When I opened the sealed box I found only 46 fasteners. Frustrated and with time running short, I simply ordered another box of 50 to get the additional two fasterners required. When the second sealed box arrived, I opened it and counted the number of fasteners. Again, I received only 46 fasterners in a box clearly marked 50 screws. Finally, e-mail was sent to FastenMaster for their explanation. Two weeks later ... no answer. My suggestion? Try another brand/syle. They are out there, and from my experience they might even work a little better. If you choose to use this product, be prepared for a possible 8% shortage.

Better grip and easier to use in timbers

I highly recommend these screws. First, they are long enough and strong enough for most (perhaps all?) household apps; cabinets, tv wall mounts, etc. Second, the star drive (included in each box) means that it is virtually impossible to strip out the head. This happens all too often with Phillips heads. The big box stores charge about $1 apiece for these in boxes of 12. Get this box of 50 and you wont regret it.

Started using this type of screw for my deck rail, fencing and landscaping projects. Works great.

Finally, something to mount a hang board to my wooden studs! Worked brilliantly. Love that they come with a spider driver.

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

Excellent, heavy duty.

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.

Nothing to dislike they are the best. Im a roof contractor primary use is securing roof anchors for saftey harnesses, into a truss of course. First experience 7 years ago building a tree house. Requires little energy meaning extended battery life. Going into a harder wood the aggresive thread will pull the wide head half through the side of a 2x4 without effort. These screw are hard to find sometimes and Amazon has good prices if you shop the site. Repeat buyer every few months.
