Drive quickly, strong, wide head allows them to grab hard. DON'T lose the proprietary drive bit!
I had a couple of diverse uses for these HeadLOK screw. One use was a trim application and the other a stair repair. These screws worked well for both situations.I have a 10 foot x 5/4 x 6" piece of Bubinga transition board between my tile kitchen floor and my carpeted living room. If you're not familiar with Bubinga, the pieces I have are reclaimed 40+ year old wood that is basically Brazilian Walnut, is hard as rock, easy to machine but tough on machine tools due to it's high silica content.My problem was that over the 10 foot run, I could not pull the Bubinga close to the floor with standard wood screws because it's too thick and the Bubinga was always squeaking and flexing. I tried shims and then floor leveler. Nothing worked. Then I used these HeadLOK lags to pull it down and they worked great.I didn't mind the “steam punk” look of the wide heads on the Bubinga - it looks sort of cool (see photo). I pre-drilled the Bubinga for the HeadLOK lags - I didn't want to split a 40 year old piece of rare hardwood.My other issue was a site built basement staircase. The stair treads were pulling away from the stringers. The HeadLOK lags worked great to pull it all back together.The one thing you need to know is that the "Spider Drive" bits required to drive these lags cannot be replaced with any other bit on the planet. I literally have 200 odd sized drive bits - Torx, Allen, Torx security, 1-3 square drive, Phillips JIS and every other bit you can think of but without the "Spider Drive" drive bit, you're "unscrewed" - you can't drive these bits. That sort of sucks but these bits also drive very securely, better than Torx. I can see what customers complained about the missing drive bit in some reviews because there is no substitute I am aware of - if you know of one, let me know.In the attached photo, you can see the Bubinga trim board with the HeadLOK lags in place, I used a 17mm forstner bit to recess the HeadLOK heads so they are flat to the surface and for the first time in 15+ years, the Bubinga transition board does NOT flex or squeak. Hope that helps!

A great advancement over lag bolts well worth the extra cost. Used to install a bridge deck (pressure treated), the installation was a breeze using run-of-the-mill regular and impact screw drills (both corded and battery). A number of star drivers were provided with the quantity Of screws I purchased and I anticipated having to switch them out when stripping one due to carelessness. I used only one driver for 225 screws. Although I was prepared for it, the coating on the screws allowed effective install and drew the heads in flush or below the surface, thus no predrilling or countersinking was required. Out of the 225 screws, two were unusable due to extra material (not sure if metal or coating) Impeeded the driver from engaging the head. Time will tell if the screws hold up to the pressure treated lumber better than the hot dipped galvanized bolts used elsewhere on the bridge. I anticipate they will do better but I’m 66 and maybe my grandkids will find out. A contractor friend recommended these over lag bolts and I’m truly grateful for the advice.

Reviewed in the United States on July 21, 2015
These screws are fantastic. I'm building a pergola and was using 3 1/2 inch Pozidrive screws, and since I didn't have a drill bit long enough to drill a 3 1/2 inch pilot hole, the screws would start camming out and stripping once they went in past a few inches.
I picked up these structural screws which use a spider drive. They are flawless. Even at 4 1/2 inches, NO cam out issues, WITHOUT pilot holes. Incredible. And the wide flat head works like a washer. Like the box says, these pretty much can replace 3/8 lag screws + washers. Awesome. Flat black color looks very clean too.
