### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    These really bite (into the wood)
  

*by D***U on Reviewed in the United States on September 26, 2024*

These screw in easily without a pilot hole and really pull the wood tight.  I prefer the bolt head, but these are better for flush mounting behind joists and such.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great screw

Perfect for outdoor wood projects. Connecting wood to wood is the best use for this item.
