   Drive ankors... They're every where including the big boxes.

    

   Who ever invented work didn't know how to fish....

   drill a 3/16" hole ,put in a 3" piece of rebar tie wire in the hole and drive a 16 common or a 16 doublehead in the hole. works just as good only cheaper.

   Rawl makes a line they call "spikes".  Rawl spike, form spike (double headed), lite spike, stainless steel lite spike. The figures on their holding power are very impressive. The only down side is that they are difficult to remove once set.

   A common term for these units seems to be "deformed nail, spike" type of anchor.

   Thanks. I kept looking for Concrete ANCHORS instead of spikes.... I found Rawl's website and phone number.

   I call them for a local distributor tomorrow.

   FWIW, neither Lowe's or HD carries them or anthing like them - at least not in my area.

   I like these........They're called "Striker Bolts"........

   All you do is drill your hole, hit the small pin, and it expands the bolt..............

   Pretty cool Huh?

   I have only seen those in nylon/plastic and lead, and not with the nut.  Looks like a useable item.

   Do it right, or do it twice.

   HILTI quik bolts are amazing, used them for years instead of setting anchor bolts in the fresh concrete, cleaner, easier, safer....a little pricier but not bad.

   As far as nails I've always drilled a 3/16 hole then stuck a peice of tie wire in the hole and nailed with a 3-1/4" spike, it holds real well and you can remove it easily.

   That's been my choice for a long time.  If the concrete is of sufficient depth, I usually drill the hole over-depth, set the nut to full thread contact and drive the whole assembly tight...don't even need to put a wrench on it.

   Only thing to be aware of on these and others like them is to stay inboard of edges far enough to minimize blowouts.

   any idea where to find the female version of those?  i can't find them any more- they were my favorites-  looked pretty much the same as the male version in your picture from the waist down, so to speak, but instead of a pin to strike, they had a lead? slug in the bottom that you upset by putting a smaller bolt or rod down in it and hitting that with a hammer (fyi- you will only forget once to hold the rod or bolt with a pair of pliers, not your bare fingers!)

   i liked them because you could drill to the exact same depth as the anchor length, without guesstimating how far the cone-shaped plug would go up the bunghole on the other type with the break-away collar- which are often a B!TCH to actually get to shear off without loosening the anchor in its hole or spalling the concrete around it.  also, they were fairly thin-walled.  for example, 3/8"-16 size needs only a 1/2" hole- not 9/16" like the break-away collar type (9/16" sds bits not being all that common around here)  and they were pretty short, making for much shallower holes in the floor- less likely to punch thru the slab in a residential basement or garage.

   thanks,
