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

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

What can I say? They are fasteners.

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.

Used on every deck I build

comes with spider bit, tough structural screws

Great product

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

worked like a charm!

Easy to use and really convenient

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