These are stainless steel knurled pins made to a customer’s print at a quantity of just over 500 pieces.  They measure approximately .800″ in length at a diameter of .118″.  Ofcourse the most interesting requirement is the diamond knurling of .150″ at each side that is intended to bite into the plastic setting.  In order to increase the diameter at the knurled ends and allow for better locking into the plastic the factory adjusted their method to allow for very aggressive knurling, thereby pushing the material further and increasing the overall diameter at both sides.  No machining or deburring was done on either side after this process to preserve this increased diameter.
