Temporary Concrete Connections
This method is easily removable and won’t spall the concrete.
Here’s a method for temporarily attaching wood to concrete. It requires a 3⁄16-in. hole bored into the concrete, and then you put a scrap of 14-ga. electrical wire in the hole before driving an ordinary #8 by 3-in. screw. As you drive the screw, it cuts into the copper and plastic sheathing and wedges tight. The bonus is that it’s easily removable and won’t spall the concrete.

Nice tip.
That’s clever.
Having worked in the field of concrete construction for many years, the same technique is used with rebar tie wire and 16d doublehead nails. TapCons are also just as simple and typical one just drills thru the wood into the concrete then screws in the TapCon. Hilti made a special drill bit with a slip-on hex driver for the TapCon (or their fasteners).
