Affordable, Useful, and Expendable
I've yet to test the accuracy and the quality of the product. But say if it does work thenthis thread & nut identifier is affordable, portable, and expendable if broken. I was thinking of getting the more expensive ones that also mount onto a vertical surface or table. But then I thought "what if the threads are in a vehicle per se" so this will be of great use for such a situation. I may think about buying another so I can cut them off the wire cable and place them in another container so I can use these in even tighter spaces where the whole bunch just gets in the way when I only need one.I see two things that concern me but don't exactly impact the use. Which are based on some reviews on the swage sleeves breaking. I saw the quality of crimping and it ain't good but then again I can't fully argue because the item, after all, is cheap. But if oneself has the right tools and the right knowledge, it actually is repairable if that oneself has the right tool and knowledge. But again unfortunately not everyone has these.the second concern are the plastic spacers, the last time I've seen these was in kindergarten or grade school. They may break later down the road but again is repairable/replaceable just need to go to your local hardware store and get plastic spacers.But overall it is great, again I've yet to encounter any issues with this but hopefully not cause I've visually checked each thread/nut for damages or abnormalities so far looks good but physically I cannot yet say.And again if this ever breaks later down the road (way pass the eligibility of returns) then I can always purchase another one.

Reviewed in the United States on August 23, 2023
Don't guess anymore,.this is a good set. The only thing is having all of them together on a wire. I fixed the problem real quick. Get a magnetic bar from harbor freight and put them on it. What a time saver and you can keep them all handy.
