Concrete Sub-floor in Kitchen


I have had a lot of problems trying to fasten something to the kitchen
sub-floor because it is concrete. The special screws they sell at the
hardware store do not work; the concrete nails do not work either;
all the special items I buy, I end up throwing away because they simply
do not really fasten anything. I hope you may have some suggestions
as to what type of special screw really works on concrete.
Thanks in advance.

What are you trying to lock to it? Maybe a mastic of some sort would work better than a mechanical fastener.

evidently its harder concrete compared to other strengths,,, if conc screws aren't working, you may need drop-in's ( lags into lead or plastic expansive shields ) or mastic as klinger sez,,, caution for the future - holes're easier to patch than it is to remove mastic

Ayuh,... I'm wondering if it's your Technique, rather than the fasteners...

I've had Great service from Tap-con screws...

The issue is with you, not the fasteners. You're either using the wrong tools or technique or both.
If you detail what your doing and with what materials and what tools, we can direct you.
Saying you tried everything and nothing works is not helpful information.

That is a good point.

Mastic is also a food source for mold. I wouldn't recommend it.

Best way (imo) is drill a hole in the concrete (rotary hammer preferably, hammer drill if desperate), then sink in a GRK Caliburn screw:

Without knowing the depth of concrete, it is hard to recommend a technique. Options for fastening to concrete typically include Ramset 38 nails, Tapcon screws, lead shields with screws, plastic inserts with screws, or concrete screws. Each of these methods will work with proper technique, however the most effective method depends on the thickness and strength of the concrete.

Oh. Another reason to not "glue" on concrete.
