Hi All,

Recently, we have received complaints from our customer that the thread condition of our dispensing tools are NO GOOD. Meaning, it doesn't fit into their standard thread gauge when inserted. FYI, my company and our customer uses the same inspection tool (the same brand as well). Just a month ago, our customer's QC head went to our plant and discussed this matter with our QC manager (including me also). We checked the condition of our thread gauges and not surprisingly, the result was, that some of them are "NOT IN GOOD CONDITION" anymore. I may agree on this finding, at some degree, because our plant had never performed any maintenance or calibration of our thread gauges. But I would like to ask for a more reliable and accurate way of performing such procedures. You see, when our customer's QC  made that conclusion, the method he used was only visual inspection and BAAAAAAMMMM!!!!! there goes his findings. He even recommended me to do the same for the rest of our gauges. I know that this method is not the proper way of evaluating the "fitness" of an inspection tool, so guys I need your expert advise on this.

Thank you.
