圓頭螺絲，00-90 x 3/8 英寸，25 入

Just got these for a small electronics repair project — the 00-90 threads are surprisingly crisp and catch perfectly on first try in brass, no stripping. They’re tiny but the round heads sit flush enough for what I needed.

Brass heads and clean threads make these perfect for the little clock hands I was fixing—they seated flush without any wobble. For the price, you get solid US-made hardware that's exact to spec. Exactly what I needed.

Had to replace some tiny screws in an antique clock, and these brass round heads matched the originals perfectly. The threading is clean and each one seated smoothly without stripping.
