Tapcon screw tips?
I've just bought a block and stucco house and need to install shelving, etc. I've had little experience with drilling in concrete, I'm used to wood studs. I looked into buying one of those guns that shoot nails into concrete, but the salesman at the big box store said I'd be happier just using the Tapcon screws. It took me a while to figure out the hole has to be drilled deeper than the length of the screw, and those drill bits only last a couple of holes (went through $12 in bits putting up one shelf). Any tips to using these would be helpful. Small projects turn into hours of frustration!
