Concrete "nail"
dickydee

I watched an episode w/ Tom helping someone insulate and fir out a concrete basement wall. He drilled holes in the wall and drove in what looked like a thick nail with a "kink" near the end. The "kink" is what held the "nail" in the hole. I have been unable to find these and I don't have a name for them so that I can search for them.
Any help will be appreciated.

if the nail kinks it losing its holding strength this information wasnt given correctly. strikers are supposed to be driven straight in.

personally i drill a 3/16" through the wood into the concrete about 3 inches deep, then insert 2 or 3 strands of 16 gauge tie wire then drive a normal hand spike. the wire will compress and tighten the spike thus providing the holding *****. this is the most cost efficient method and is readily used in both residential and commercial construction applications

Generically they are called drive anchors. There are lots of different styles. The one you describe is one of them. Red Head makes them and other companies too.
*****s Fasteners make a rawl spike.
Jkirks method is suitable and probably cheaper for simple wood furring

Check the for this Fastening Handbook.
*****s Fasteners ( www.*****s.com )
Look at page # 22 Cat No 5502 thru 5577
SpikeAlso check Split Drive Type Cat # 3031 thru 3781.
Than there is a Hammer-Screw ( we call this one a drive pin )
