#3 Square Six Inch Driver Bit

After driving 8 of the concrete screws supplied suggested by Deckgo (installed in an 8" deep 3/16 hole as advised) the tip of this bit broke off mid drive. It is not a quality tool. Suggest you just buy a 6" extension (universal) and the #3 bit end elsewhere.

The tip of the #3 square driver bit broke off on the first use and remains wedged in the head of that screw. This item does not appear to be a well-made product for the torque generated by the better drivers that are often used for larger #3 tip screws.

3 stars because the first one we used the head snapped off. Then I had to order another. I did get a replacement free of charge.

these Robertson bits/heads far exceed the grip of a Phillips head and even a Torx bit

These screws are powder coated unevenly and often partially fill the heads making stripping them out very easy. I also had several break off heads when tightening and many more strip out very easily while using a 12v impact. Do yourself a favor and just buy hardware locally
