Review on High-Quality M6 Carbon Steel Rivet Nut Rivnut with Flat Head and Threaded Insert - Pack of 50, Yellow Zinc Plated Finish, Knurled Body by Zach Edwards

As a result of my tests, I determined that these Carbon Threaded Rivetnut Knurled Fasteners are not worth the money. The knurling is too shallow and easily stripped, making it difficult to get a good grip with any tools. It's frustrating that such a small item can cause such big problems. The only positive is that they come in a variety of sizes. Unfortunately, I will not be purchasing again. Tools and Home Improvement should focus on better quality materials for such a crucial component of DIY projects.
