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

These are wonderful bolts. Go in like silk without having to drill pilot holes. Pull in very tight with no slipping.

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.

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

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.

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!

Love these. Very strong.

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

Great product

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

Awsome...plain and simple.
