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

worked like a charm!

Easy to use and really convenient

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

They worked great.

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

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

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!

Great screws for attaching furring strips through continuous insulation sheeting on house exterior to studs. Only issue is that if they didnt give you three bits for the spider drive you may be out of luck because my impact broke the first bit about half way through. But since they give 3 bits you should be good.

Was a bit concerned when I saw the price of these for the quanity compared for what I had been paying at a local large do it yourself store. Pail they came in is nice, good quality screws, will be ordering more only larger quanities next time at this great price.

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.
