براغي رأس مقبس M6-1 × 50 مم | رأس منخفض محرك سداسي المقبس | جزئية الخيوط | فولاذ سبيكة فئة 8.8 (1000 / عبوة)

The low head profile on these M6 screws let me fasten a bracket in a tight spot where a standard cap screw wouldn't have cleared. Partial threading made alignment a breeze, and all 1,000 arrived with clean threads and consistent finish.

Used a handful of these for a jig build and the hex socket drive gives a really solid grip with no stripping. The partially threaded design made alignment much easier than fully threaded screws.

Got a thousand of these for a tooling fixture build and every single one seated cleanly without any stripped heads or galled threads. The partially threaded design gives just the right grip for clamping down 50mm of steel. Class 8.8 hardness feels reassuringly solid for the price.
