FH-160-5ZI | مسامير تثبيت ذاتية من PEM | فولاذ مطلي بالزنك (5000 / عبوة)

The zinc plating looks even and clean across all 5000 pieces, and they seated perfectly flush in the sheet metal on the first try. These studs have held up through a full day of assembly without a single burr or misalignment.

I was worried about stripping threads on thin sheet metal, but these studs installed cleanly and have held firm through several assembly cycles. The 5000 count will last me a good while.

The zinc plating is holding up really well so far, and these studs press in cleanly without any wobble. For a bulk pack of 5000, the consistency in threading is impressive—I've only had one reject out of the first few hundred.
