Alright, let's get into these workhorse nuts. We're talking 100 pieces of #8-32 serrated flange lock nuts made from tough carbon steel with a bright zinc finish that fights corrosion. The secret sauce? Those serrations on the flange bite into surfaces creating serious anti-vibration action - these babies won't loosen up on you. Perfect for machinery, furniture, automotive stuff, or any project where things need to stay put. Quick heads up - because of the serrations, skip the washers and don't use them on surfaces you don't want scratched. Installation's simple: line up the threads, wrench them down (tools not included obviously), and you're golden. Specs: 5mm height, 8.5mm hex width, 12mm flange diameter. Basically if you need reliable locking action without the hassle of separate washers, this 100-pack has you covered for multiple projects. Solid value for serious fastening jobs.
