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

Ive always hated the normal nails and screws you find at Home Depot and Lowes. These things from FastenMaster are definitely the way to go. There is no need to predrill holes and they really bite into the wood. I love them!

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

Works great, strong.

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

I used these screws to secure 1x4 furring strips in a rain screen design on the exterior walls of a new construction house. The work great for that purpose and I am confident in their being able to hold up over the long term. My guys were driving them through the 1x4s, 2 of foam board, 1/2 plywood and into 2x6 studs with a 1/2 cordless drill but I would suggest an impact driver or pre-drilling the holes for a much easier time and mush less splitting of the 1x4s or 2x6 studs.

They worked great.

What more can I say about big screws, they worked.

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.

These have become a staple around our property! They work great and we have purchased multiple lengths. You do need an impact drill.

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!
