براغي رأس مقبس M8-1.25 × 90 مم | محرك سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 18/8 (100/عبوة)

Finally, a machine screw where the hex socket doesn't strip under high torque—these 90mm partially threaded ones held perfectly in my jig. The 18/8 stainless feels solid and corrosion-resistant for the shop environment.

Finally got around to using these for a machinery guard repair, and the partially threaded shaft made alignment much easier than fully threaded bolts. The hex socket drive held up nicely to my torque wrench without stripping.
