براغي قطع الخيوط من النوع F #4-40 × 3/8 بوصة | رأس مسطح مع محرك فيليبس | فولاذ مطلي بالزنك الأسود (200 / عبوة)

The black zinc coating is a nice touch—gives these tiny screws a clean, uniform look that resists rust well. They drove smoothly into the metal bracket without stripping, which surprised me for the size. Exact fit for a small electronics repair I was finishing up.

I needed a small batch of #4-40 screws for a DIY electronics enclosure, and these cut their own threads perfectly into the plastic. The flat head sits flush without cracking the material, and the black zinc coating hasn't shown any wear after tightening with a Phillips driver.

The black zinc finish looks professional and hasn't scratched during my assembly work. These little #4-40 screws bite into the metal right away with the thread-cutting design, and the flat heads sit flush just like I needed.
