FastenMaster FMHLGM412-250 HeadLOK Heavy-Duty Flathead Fastener, 4-1/2 Inches, 250-Count,Black

Works great, strong.

I love them. Im a carpenter. I build decks. I use these anywhere code allows. They hold really good and when visible, they are easy on the eye. They are treated lumber and cedar friendly. They dont corrode or stain. In most cases, you dont need to pre-drill. Ive used them in a lot of different lengths ranging from 2 7/8 up to 10. One word of advice, you do need an impact driver, a regular drill-driver wont drive these.

Awsome...plain and simple.

There where quite a few missing the threads in the bucket. Probably A dozen or more.

Came with three 6 point star bits instead of an 8 point for some reason, had to go buy another set of bits. Worked well for my application other than that.

Although they are a bit Pricey, they are without a doubt the best holding screws Ive ever used and I have used them all. They go in rather easily , draw up tightly and hold like the wood was welded. Great Product!

Love these. Very strong.

Easy to use and really convenient

Perfect fasteners to add a structural LVL beam. Very low profile head so you can Sheetrock over the top of the screw heads !

These things, in any length are great, work well and hold awesome!!!
