Set Screw, M2x4, Slot Cone Point

Was a perfect fit for the spindle coupler on my mini lathe. The cone point seats nicely into the dimple, and the M2x4 length aligns just right. No wobble after a week of use.

Finally got the right fit for my mini lathe project — the M2x4 thread was exactly what I needed for those tiny adjustments. The slot cone point held securely without stripping, which surprised me given the small size.

The cone point on these M2x4 set screws bites nicely into the shaft, keeping everything secure. I used them to lock down a small gear, and they haven't backed out yet. Only minor quibble is the slot could be a tad deeper for easier tightening.
