Gewindestiftschraube, 8-32 x 1/4", Sackloch-Kugeldruck, selbstsichernd

The dog point tip seated perfectly into the alignment hole on my fixture, and the self-locking bite held firm through a full hour of vibration-heavy milling. I've used cheaper set screws that stripped or backed out, but these stayed rock solid and the 1/4" length was just right for my setup.

The self-locking feature kept these screws firmly in place during a tough machining job, no backing out at all. The 8-32 x 1/4" size was exactly what I needed for precise bench top alignment.

The dog point seated perfectly in the alignment hole on my mill table, and the self-locking action held firm through a full afternoon of cuts. I grabbed a handful of these 8-32s for precise positioning jobs, and they've been dead reliable so far.
