HOLO-KROME 76151 براغي رأس كبس M5-0.8 × 65mm | محرك سداسي | فولاذ سبائكي أسود حراري (100 / عبوة)

The black oxide finish held up perfectly against my jig setup, even after repeated adjustments with a hex key. Each screw threaded smoothly into tapped holes without any binding, which saved me a lot of time on this project.

These M5 screws torqued down cleanly into my jig setup without any stripping, and the black oxide finish hasn't shown a single speck of rust after a month in a damp shop. For a hundred pieces at this price, the socket drive depth feels exactly right for a standard hex key, and every one seated flush

Threaded a full row of these into a mild-steel fixture and the black oxide finish held up without a single gall. The 65mm length seated perfectly, and the hex drive bit slipped in snug every time. Exactly what I needed for a precision assembly.
