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

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

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.

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!

Easy to use and really convenient

I love them. Im a carpenter. I build decks. I use these anywhere code allows. They hold really good and when visible, they are easy on the eye. They are treated lumber and cedar friendly. They dont corrode or stain. In most cases, you dont need to pre-drill. Ive used them in a lot of different lengths ranging from 2 7/8 up to 10. One word of advice, you do need an impact driver, a regular drill-driver wont drive these.

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

Worked great

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.

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

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