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

Worked great!

These are hard to find at our local hardware or Home Depot and when I can get them they charge premium price, so this is a great deal for me. I use them for barns, out buildings, fencing and other general projects around the farm. Using the HeadLock fastners ensure that what we build stand up to the abuse of the elements and animals. They pull warped boards together without going in deep like the smaller heads do. These have been the best damn screws we have found.

The best screws. Great quality. V easy to use

These fasteners are a great alternative to using standard lag bolts. They are easier to install and seem to hold up very well. I have used them in several different applications and have not had any issues yet.

love these screws use them in a lot of projects now

Better grip and easier to use in timbers

Price was good, delivery was good. They are as advertised and worked great in my application screwing gable trusses to the side of my shop to attach a roof to cover my doors. There was 50 in the box and there was a driver in the box.

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.

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

These are cool. What else can I say? Don’t lose the bit.
