*by S***E on Reviewed in the United States on May 15, 2017*

### ⭐⭐⭐⭐⭐ 







  
  
    hard to find item
  

*by L***S on Reviewed in the United States on September 6, 2019*

Locally these are hard to find item. Looks like fine craftsman. They are hard. I had little trouble cutting some shorter with my hand cutter which I usually cut 6-32 and 8-32 bolts with. Bought plenty but will buy again if needed.
