براغي رأس سداسي M6-1 × 40mm | محرك سداسي برأس منخفض | خيط جزئي | فئة 8.8 سبائك فولاذية (1000/عبوة)

These hex socket screws fit perfectly into my jig setup without any stripping issues. The partially threaded design really helps hold everything tight under vibration. For a bulk pack of 1000, the alloy steel quality is exactly what I needed for ongoing tooling projects.

I’ve been using these for a few months now on precision tooling, and the low head profile saves space in tight spots. The class 8.8 hardness handles high torque without stripping, even with repeated adjustments.

These worked perfectly for the jig I was building, and I appreciate the partially threaded design for clamping applications. The hex socket drive made installation straightforward with no cam-out issues, and the 1000-count box means I won’t need to reorder anytime soon.
