براغي ذات رأس أسطواني M4-0.7 × 14 مم | رأس مسطح بمحرك سداسي | ملولبة بالكامل | فئة 10.9 من سبائك الصلب مؤكسد أسود حراريًا (1200/عبوة)

Finally found M4 socket cap screws with a consistent hex drive that doesn’t strip—these fit perfectly for my jig adjustments. The 14mm length is just right for securing brackets on my tooling setup.

The thermal black oxide finish on these M4 screws gives them a solid, professional look, and the hex socket drive made installation into my precision jigs effortless. I've already used a few hundred and they all thread smoothly without any binding.

Bought a 1200-pack for a batch of jigs and I’m already on my second project with them—the thermal black oxide finish hasn’t chipped or rusted at all, and the hex socket drive grabs cleanly every time. The class 10.9 alloy steel feels rock solid, a real bargain for the count.
