Review on 🔒 binifiMux 20-Pack M8 X 1.25MM Nylon Lock Nuts - 304 Stainless Steel, Hex Inserted, Self Clinching, Silver by Andy Hearshman

I don't know where these good reviews are coming from. I intended to use these jam nuts to thread onto the bolt leaving about an inch of the end of the bolt open to install another bolt or item of the same span. The first 2 worked great. The next three went as far as they wanted, maybe half. I couldn't move or take them out. I tried prying them off with a pry bar and the bolts clicked without even moving the nuts. I lost 3 rustproof M8 bolts and a couple worthless nuts.
