nice product
These work as advertised. Nice aggressive tip easily penetrates pressure treated lumber. They are a bit on the expensive side, but appear as a stronger alternative to the Fastenmaster brand 'Headlok' screws.

Withstands Heavy Torque
I used these 8" screws to connect together railroad ties. I drilled a countersunk pilot hole through the first tie so that the screw only had to screw through about 4 inches of the second tie. Dish soap helped for lubrication. They stood up to torque from a standard battery powered impact driver, an electric drill, and final hand tightening with a ratchet. None of the 50 broke. The Torx heads didn't get deformed or chewed up either, and the included Torx bit was still in perfect condition after driving all 50 screws.

Buy with confidence
These are great! They really drill right into the wood easily and make a strong connection! Zero complaints!

A Little Pricey
Used these instead of through bolts on guard rail posts on my deck along with blocking. Drove very well with an impact driver and seem to be sturdy. Hope the coating holds up. Supposed to be better than galvanized. Time will tell

Better than Timberlocks
I'm building a timber-framed structure, I'm using these in place of lags or pegs
