براغي رأس مقبس M8-1.25 X 18mm | رأس مسطح محرك سداسي | ملولبة بالكامل | فئة 12.9 سبائك فولاذ أكسيد أسود حراري (300/عبوة)

I needed a batch of these for a fixture build and the hex socket drive made installation much faster than dealing with stripped Phillips heads. The 12.9 alloy steel feels reassuringly tough under the wrench, and the black oxide finish gives them a clean, uniform look.

Pulled these out of the package for a jig I’m building, and the hex drive seated perfectly without any stripping. The 12.9 alloy steel feels seriously sturdy, and the thermal black oxide gives them a nice, uniform finish that resists scratching during install.

The thermal black oxide finish is holding up nicely so far, no rust after a few weeks in my shop. Threads are clean and the 12.9 alloy steel feels plenty rigid for my jig builds. Only wish they came in smaller pack sizes, but 300 will last me a while.
