Using the 2×4 example mentioned earlier, the maximum length tap con is determined by adding the thickness of the 2×4 of 1-1/2” + 1-3/4” = 3-1/4”.
Why do Tapcons break?
The base material may be too abrasive or too hard for the threads of the tapcon to tap. The base material may be too soft or sandy and not allow for the tapcon threads to hold properly.
