#12-28 × 1" براغي ذات رأس مقبس سداسي مسطح | كاملة الخيوط | سبيكة فولاذ معالجة حرارياً باللون الأسود (100/عبوة)

These flat heads sit perfectly flush in my fixture plate, exactly what I needed for a clean assembly. The black oxide finish looks nice and the hex socket grabbed securely without stripping.

Installed these in a small jig today, and the hex socket drive made them easy to tighten in tight spots. The black oxide finish feels durable and the threads cut cleanly without binding. Exactly what I needed for precision assembly work.

Used these for a jig I’m building, and the hex socket drive makes tightening them in tight spots much easier than a regular hex head. The black oxide finish looks clean and seems durable, but I wish the threads were a bit smoother out of the box.
