HOLO-KROME 87203 براغي قبعة بمقبس M12-1.75 × 100 مم | رأس مسطح بمحرك مقبس سداسي | فولاذ سبائكي بأكسيد أسود حراري (50 / عبوة)

Used a handful to mount heavy steel brackets for a workbench, and the black oxide finish held up well against the wrench without any stripping. The socket drive made installation much easier than a standard hex key would have.

Installed all 50 on a fixture build with a hex key, and the alloy steel threads cut cleanly every time without a single stripped one. For the price per piece, these are perfect for jigs and tooling.

The black oxide finish handled grease and grime on a press tooling setup without any staining. These M12 cap screws threaded in smoothly with a hex key and held solid at torque.
