## Questions & Answers

**Q: how many are in the package?**
A: 25 per box, clearly stated in the heading!

**Q: They say dry enviornment? Can these be used to secure a gazebo to a concrete pad?**
A: I would say yes because it's not constantly wet. If the concrete is wet most of the time it can get flaky and not hold tight.

**Q: Can this be used to attach an a/c mini-split wall mount brackets to stucco?**
A: These are perfect for any cement or stucco surface.

**Q: what size bosch concrete SDS drill bit is needed to use with these concrete screws?**
A: 3/8 inch drill size.  The bolt shaft is a hair under 3/8 inch an the thread diameter is about 7/16ths  You will need a 3/8 inch ratchet wrench to torque these in.  I used a power driver and snapped the adapter bit.  The holding power is amazing.
