Hello Josh,
We appreciate your question. The hammer-set nail drive concrete anchors can be used to fasten 2x4 lumber to concrete, block, or brick base substrates. Please ensure that one of the three base material mentioned are beneath the tile and thinset and the the minimum embedment is met. The minimum embedment for a 1/4" diameter hammer-set is 3/4". embedment is measured from the split (wedge) tip, not the mushroom head. The actual dimensions of 2x4 lumber usually measured 1.5" x 3.5". Assuming you are attaching from the 1.5" side and minimum embedment is .75"; this will leave .75" for the thinset and tile floor thickness. Please make sure that the thinset and tile floor does not exceed .75" or the anchor will not meet minimum embedment.

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by RedHead Bolts R GR8! I have found that Red Head anchors which you install "Chicago-style", i.e. with a hammer; install easier than the screw-type anchors that often come with a product. Where screw-type anchors often get twisted off (especially in older concrete that is pre-1991), leaving you with the headache of extracting the remaining shaft. With RedHead's, just insert in the hole, tap into place on the lower collar with a common screwdriver, and then WHAM! one or two hits directly on the head, and job done! Don't ask me to explain the diff 'tween 'old' and new concrete, all I know is working in older concrete or bricks isn't a problem for me anymore. July 12, 2016
