We want to know what the customer is using to measure the thread depth over 12mm,<br>Because we used the tooth gauge in our factory to do the test, the test results are as follows<br>Of the 49 "3", 15 were OK, 34 were not OK, and 4 "29 were OK.<br>The cause of the defect is not the thread depth but the pitch<br>(because even if the thread depth is very deep, it will not affect if the lock is not in.)<br>In addition, we will return the good products to you, and we will send the defective products to you again.<br>
