براغي رأس أسطوانية بمفتاح سداسي M2-0.4 × 14 مم | مفتاح سداسي داخلي | خيط كامل | فولاذ سبائكي درجة 12.9 مطلي بالزنك (600 / عبوة)

These are holding tight in a small press fixture I just built—the hex socket drives cleanly without stripping, and the zinc plating gives them a nice, uniform finish. The 14mm length was exactly what I needed for this particular assembly, and having 600 in the pack means I won't run out anytime soon

Exactly the right length for my jig builds, and the 12.9 alloy steel feels rock solid when I torque them down. The zinc plating has held up fine so far, no rust after a few weeks in a slightly damp shop.

The hex socket drive seated perfectly on my driver without any wobble, and the zinc plating looks clean and uniform across all 600 pieces. Threads were crisp right out of the bag, no burs or binding when I test-fit them into a precision assembly.
