## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    worked great at 90 degrees....not so well on an angle
  

*by M***E on Reviewed in the United States on July 30, 2020*

At 90 degree the cups work well with #10 screws, if your screw is on a slight angle to the face of the wood the screw will easily pull through the cup washer.

### ⭐⭐⭐⭐⭐
