These worked great for my outdoor project where I drilled and epoxied them into a cinder block walk! The threads are clean and I had no issues putting my eyebolt fasteners all the way through them without tools! I cleaned them first using IPA. My project turned out great and looks amazing! I bought these because I want my job to last! The top two wires are actually extension spring (so I don’t pull the wall over and they have lobster clasps on them so they can be removed for access). I hope this helps someone. Cheers
