Review on POWERTEC QTN1102 Pronged 4 Inch 20 16 Inch by Bobby Washburn

I bought these nuts to attach tie down rings to a trailer. The inside of the trailer wall needed to be flush and a tee was the perfect solution. We all know that screws/machine screws come in standard half inch sizes and because the thickness of the material I threaded the screws through didn't match the size. Exactly, I'd have to shear the bolt/screw to make sure I had enough turns to secure the fastener. screw. I have lubricated each fastener with Loctite and they are perfect for my application. The price is good but I have 15 of these that I don't need. Don't worry, I'm sure that one day I'll finish a project that requires 16 of these. 2 years later I just ordered another box of 50 because, you guessed it, I need another 20 for another project. The two year old nuts discussed above have weathered since installation and I have not observed any corrosion on any of them. up to 6 stars.
