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

When i saw this nail straighten out a bowed 2x4 into a stud i was seriously impressed. Ive looked all over my house to see where else i could use these they are so much fun to use. Ended up using these to attach a TV mount to a wall.

Great value and excellent screws. Performance is exactly as advertised. We used them to assemble raised beds and a surround for our shed. Definitely use an impact driver for efficiency.

great screws. I used these to secure pieces of 2x4s when building shelves. I did have to drill pilot holes when screwing near ends of the lumber as the screws split the wood when I didnt drill pilot holes

Not only did these work very well - I needed to add some 4x4 supports for a cover to an existing deck - but they look good one installed. Not something youd normally credit to a screw. Worth the money.

I use this product for making quick tables, support shelves and even wood hassocks. Notice the head configuration....You can quick assemble 90 degree wood joining...just drill a small home in the edge of the lumber and the other board. Screw them together with the fastener and you discover the joint is quite strong. I suggest that they be used on real lumber and not MDF board. The screw heads are quite presentable and actually look decorative. Im always looking for better ways to join wood pieces together.

i use these screws for fastening kitchen islands to the floor,ive been using these screws for this for sometime,pretty much since they came out with them,they are perfect and amazing this is the first time having bought them online,,, i now find myself trying to figure out how to kick myself in the butt for not buying them here before ive been purchasing them at one of the 2 popular hardware/lumber chains since using them and it is the exact same product but at a fraction of the cost,,,,cant beat that

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

Use these screws extensively on a deck. Biggest plus is the flat head.

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.

works great, so much better then using bolts when building a deck
