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

Works great, strong.

Great product! Already wrote review on 2 7/8 same results luv them.

Used on every deck I build

Love these. Very strong.

The large head, and ease of driving make this product a winner for installing ledgers, stair rails, and many other uses.....great rating for structural holding wins bonus points with inspectors...excellent product for both remodel and new construction! Would recommend it to anyone in the building business! Jim Gregory

Used to build a deck, these things literally saved the day, Ill continue to purchase these for any large wood project that I have to work on where full support is needed/required (deck footers/stairs/railing). Awesome product at a decent price (fairly expensive, but time saving).

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.

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

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

I love these. They looked great on my new cedar raised beds and they have a lot more gripping power than a traditional wood screw.
