Ava ★★★★★

The threads on these #0-80 screws are cut cleanly, so they seat without any wobble in my jig fixtures. The 18/8 stainless finish looks sharp and the flat heads sit flush every time.

Sophia ★★★★★

I was pleasantly surprised by the precision of the hex socket drive on these tiny screws—they seated perfectly in my jig without any stripping. The 18/8 stainless steel feels robust and corrosion-resistant for a project I'm building.

Adam O. ★★★★★

Finally, a bag of tiny screws where the threads are actually clean and consistent—no frustrating cross-threading. These #0-80 flat heads seat perfectly flush in my jig build, and the 18/8 stainless gives me confidence they won’t rust out.
