  • Made a bamboo pergola!
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! ... show more

  • Great security measure
Using these when securing hasp less security hardware. Can't be removed from the outside as long as you use lock hardware that has square holes for installation. I used stop nuts and flat and split washers on the inside of my shed door.

  • Not Domed Headed
These do not have smooth domed heads as indicated in the description. Also, the heads are smaller than those that I am replacing. Refer to photos. I sheared one of the bolts by over-tightening it. However, I think that they are adequate for my garage door.

  • Not what you need for wheel barrel repair
Suggested as a purchase for wheel barrel repair, not the correct ones for the hardware. 3 different lengths are needed and these need to be 3/8" not 1/4"
