### ⭐⭐⭐⭐⭐ 







  
  
    Good Quality
  

*by M***E on Reviewed in the United States 🇺🇸 on March 21, 2023*

I searched long and hard to find the exact length of bolt needed to complete a table build. I needed 1 3/4" long bolts and most everyone else only had 1 1/2" or 2". These are very well mfg bolt with smooth threads.

### ⭐⭐⭐⭐⭐ 







  
  
    Hex head 304 stainless steel 1/4 inch bolts
  

*by S***S on Reviewed in the United States 🇺🇸 on September 28, 2022*

These 304 stainless steel hex head bolts are true to the dimensions described in the description. They are a better price than the local hardware store and the same quality. Plan to use these to fix an outdoor grill so they should do the job.

### ⭐⭐⭐⭐⭐ 







  
  
    Work perfect.
  

*by J***. on Reviewed in the United States 🇺🇸 on September 24, 2020*

They fit and are the exact dimensions needed.  I needed them for my cub cadet mower.  The bolt I needed was $11 for one single bolt and a couple of washers.  So when I found these I figured I'd try them out.  They work perfect and fit exactly the same as the other bolt.  Seem to be just as good of quality as the one I lost when I was repairing my mower.
