Tapcon not holding?

Hi all,

I'm trying to put up a short section of fence along the drive way. I have a fence post holder (made out of plastic from the home hardware store), which takes four tapcon screws (? they are screws for cement at least, and have a hex top). I drilled a hole with a 3/16th bit (the screws say they are 3/8ths mind you...) about 4-1/2 inches (screws are 2-1/2"ish). When putting the screws in the threads seem to strip away to nothing - is my hole just too small? Once fully inserted, the screws come out fairly easily leveraging the fence post.

What's the best method of proceeding - should I just get more screws and a 3/8 bit and use the same holes? Or....any other thoughts as to why the screws are stripping?

Not sure if tapcons are going to hold that fence post properly for you. Maybe look into wedge anchors.

As stated, I am not sure if the tapcons are the right fastener for this job. However, you could try some longer tapcons and concrete epoxy. It also sounds like you are drilling the holes slightly larger than they should be drilled.

I agree ... tapcon may not be strong enough for this application... I would use those expansion anchors also for this type of application... depends on how strong you need, you may even need a few thick ones driven deeper...etc... good luck...

Much thanks! Picked up some wedge bolts & epoxy and everything has gone off nicely!
