    For many years I have allowed my extra bolts, nuts, and screws to accumulate, and I decided I needed to sort them in some fashion. After using the thread checker at our local supply store, I decided that surely someone sells that for the individual consumer. I ordered your thread check, and it is the perfect tool for sorting my many bins of bolts and nuts for standard and metric sizes. I am extremely pleased with your product.
