مسمار، ضبط ترس التغيير

Perfect fit on my Sieg lathe's gear train. The threads are clean and engage smoothly, so no more slipping under load. Saved me from hunting for a whole new assembly.

Had a stripped stud on my lathe's gear train, and this replacement locked everything back in place perfectly. The threads are crisp and it fit the Sieg-style setup without any filing or modification needed.

Installed this replacement stud and the change gears finally lock tight again without slipping. The threads are cut clean and it fits perfectly in the standard slot. Exactly what I needed to get my lathe back to work.
