براغي رأس كاب بمقبس M24-3 × 350 مم | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 بأكسيد أسود حراري

The hex socket drive grabbed perfectly on my torque wrench, and the black oxide coating kept rust off during a humid week in the shop. These M24 bolts held a jig steady under heavy load without any flex.

Installed these in a critical fixture for our tooling line and the partially threaded length gave me just the right grip depth. The black oxide finish has a nice consistent sheen and the hex socket seated cleanly without any wobble; they feel properly rigid at M24 size.

The black oxide finish on these M24 screws handled my jig assembly perfectly without any galling on the threads. The 12.9 alloy steel feels rock-solid, and the 350mm length gave me exactly the reach I needed for the fixture setup.
