صواميل جناح #4-40 | فولاذ مطلي بالزنك ثلاثي التكافؤ (200 / عبوة)

The trivalent zinc finish looks great and seems like it will resist corrosion well. We needed a big batch for a project, and these all threaded cleanly without any duds.

I needed a bunch for a small electronics project, and these wing nuts thread perfectly onto #4-40 bolts with no binding. The trivalent zinc finish looks clean and consistent across all 200 pieces.

The trivalent zinc coating feels even and solid, so they should hold up well against corrosion in my shop. I sorted through a handful and the #4-40 threads all caught cleanly on my bolts. Packed densely in the bag, exactly as expected for two hundred.
