براغي رأس أسطوانية مسطحة M14-2 × 25 مم | محرك سداسي | ملولبة بالكامل | فولاد سبائكي درجة 12.9 مع أكسيد أسود حراري (50 / عبوة)

I needed a high-strength fastener for a jig I was building, and the fully threaded design on these M14 screws gave me solid clamping power. The hex socket drive made installation straightforward without any stripping.

The black oxide finish on these socket cap screws looks really clean and professional—perfect for a jig I was building. They seated smoothly with a hex key and held firm under moderate torque without any stripping. Exactly the sturdy hardware I needed for precision assembly work.

The black oxide finish is holding up well on my jig, no rust after a few weeks in the shop. Only minor thing is the hex socket is a hair deeper than I expected, but they seat fine with a standard key.
