These screws require a special driver.
Would Not RecommendThe Headlok screws worked great for my application, but I hated having to buy yet another driver type. If they had made it a star drive, but sized larger than a deck screw driver, I could have covered that. As it was I was forced to return to the store, which of course had none in stock (except those included with a package of multiple screws).

Would RecommendHas good anti-corrision properties, strength, and is self-tapping. Great alternative to using lag, or carriage bolts in many applications. Available in various sizes, and lengths. I used them when completing a light pole installation.

Solid
Would RecommendI used them to fasten some 3" round wooden poles together for a garden project. They are very solid and look nice in black, which so far isn't peeling

One stripped
Would RecommendVery impressive securing the boards I was using. Had 2 more to place and the screw head stripped. Had to get vise grips and take it out. Luckily I had 1 extra. It went in fine. Probably a bad apple screw. Could not find a customer service number to report it.

In theory its nice, but still required predrilling
Would Not RecommendThey advertise as no pre drilling needed, but very tough to do yet. I probably stripped 6 of these (over a couple packets) - but still, at $1.50+ a piece, it adds up…
