[QUOTE="ndivita, post: 1455624, member: 593"] Success! I re-tapped the threads in the adjustment stem eliminating any latent cross threading. 3 mm, .50 thread pitch tap. I verified the thread pitch in the screw. I verified that the screw threaded into the tapped adjustment stem hole without the knob. I put the knob on thinking I was home free. The screw still would not thread in. Thus it had to be some dimensional anomaly in the knob interfering with mating of the set screw to the threaded hole in the adjustment stem. With a Dremel I bored out a little plastic in the knob to give a little more space in the hole and where the threads attach being careful to preserve the D shaped area. I used some bore cleaner, lined it up once more, and presto, it seated and threaded up. I used a small JIS Phillips head. Some proof that minor variations in the manufacturing output can cause real world headaches. At any rate, problem solved. In my world this is a knob job. Saved some dough as well. Thank you guys immensely for your help and ideas. [/QUOTE]
