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

They worked great.

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

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

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

Worked great

I think these are great. I use both HeadLOKs and TimberLOKs when building in VERY windy country.

Used on every deck I build

Dont know how I did without these...use them for many projects. I keep 250 count buckets of 2 7/8, 4 1/2 & 6 in stock on my construction site at all times.

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 !
