### ⭐⭐⭐⭐⭐ 







  
  
    Great Solution for Mounting Items on Cinder Block Walls
  

*by G***N on Reviewed in the United States on 10 March 2024*

Including the concrete drill bit and torx driver bit was extremely convenient. I used the screws to mount a pool cue rack on my basement cinder block wall. The installation was quick and easy. Probably overkill on the quantity but I have other applications in mind and friends that can use them.

### ⭐⭐⭐⭐⭐ 







  
  
    Fantastic on block walls and sure beats using expanding plugs
  

*by M***E on Reviewed in the United States on 15 June 2023*

So my entire basement foundation is concrete block and I like to hang stuff on the walls to save floor space.  I had been using concrete anchors that have the plastic insert and while they do work they I find them annoying because sometimes they spin in place, other times they let go....I had tried screws like this before and have had bad luck but not with these, these are so easy to use, simply drill a hole and screw them in and you got a strong connection.I just hung a new bike rack up and all the plastic wall anchors get pulling out when i would load it up and it would fall on the ground.  I moved it slightly so I could drill new holes and use these screws and no matter how hard I pulled on that rack it did not pull out with these screws and fully loaded my rack has not moved at all.So great product overall

    Manufacturer Package-ing  was poor
  

*by M***G on Reviewed in the United States on 11 September 2023*

The product is fine, but the mfg packaging was poor.  A box of 100 tapcon screws has some weight to them, yet the box is super thin and was open both at the top and the bottom.  Screws were everywhere in the amazon box.  UPDATE:  After some consumption of these screws, I have had 3 break off in the concrete.  (Yes the holes were plenty deep and blown out)  and 2 screws had very little threads and therefore would not hold.  Another screw held fine.  I ordered Torx screws, have one phllips and 1 hex head screw in the box. Geez!
