### ⭐⭐⭐⭐⭐ 







  
  
    Made a bamboo pergola!
  

*by M***K on Reviewed in the United States on 27 May 2022*

Worked great! Bamboo pergola is basically finished. Needed to stick the bamboo in flower pots for extra support because the poles are thin. These nuts and bolts 🔩 held everything together snuggly but that’s what nuts and bolts do. Just drilled a 1/4” hole with an electric drill, helped to drill a small hole first with a smaller bit then used a 1/4” bit. I needed 3 boxes of these nuts and bolts to do the job. I think I got the bamboo on Amazon too 🤔. Now all I need is my blow up pool (probably from Amazon as well) for a private, roofless tanning spot. Oh I got the curtains from Amazon too lol…jeez - hey - I’m happy!

    Amazon recommends??????
  

*by S***A on Reviewed in the United States on 23 June 2020*

I bought these bolts as part of an Amazon recommended package to repair my wheel borough. I ordered two new handles and got the "Amazon recommends", so I ordered the package consisting of new handles, new wedges, and these bolts. Well, I only received one wedge even though the photo showed two, turns out only one was ordered by Amazon. I received the bolts and upon repair found that NONE of the bolts were the correct size either in diameter or length. So, I would recommend that when it says "Amazon recommends" you carefully look at all the recommendations before ordering. I will not be returning the bolts as it will cost more in gas to drive to UPS than the bolts are worth. Lesson learned!

### ⭐ 







  
  
    Not for Wheelbarrow use!
  

*by J***D on Reviewed in the United States on 8 April 2019*

These are described for use with wheelbarrow repair along with the handles in the 'commonly purchased items' on Amazon.  These bolts are too short and too narrow for that application.  I had to go to a local hardware store to finish the project.
