Is there any special tricks in using Tapcons on hollow concrete block
walls?

I want to secure copper pipes, PVC drain pipes etc... onto my block
walls using those copper straps. I am using 1-1/2" Tapcon screws and
drilled a hole then when I feed in the screws it reached bottom and
spins. The straps are still secured in that I can't pull them out,
but I would prefer I can drive the screws in and be tight and snug.

The block walls are built with the typical 8" thick hollow blocks
with a web in the middle. I think if I drill into the solid part of
the block it's better but most times this is not practical as the pipe
may be a vertical run from floor to ceiling and I want to secure it in
say three spots and they are all in the thin part of the blocks.

Is there a trick? Will a specific size and length work best, reading
the Tapcon website it says it needs a minimum embedding depth of 1" to
a maximum of 1-3/4". It looks like the blocks are about 1" thick.
When I drill them sometimes it punches through and sometimes it does
not. I am just not doing something right so I stopped before I
drilled too many holes.

Thanks in advance for any suggestions.

Try shorter screws?

Are the screw threads the full length of the screw shank?

It is better to drill into the mortar between the blocks.
