براغي رأس سداسي مقاس M16-2 × 40 مم | محرك سداسي | ملولب بالكامل | فولاذ مقاوم للصدأ 316 (25 / عبوة)

The threading is perfectly clean all the way down, so they seat flush without any binding. I used them to bolt down a heavy fixture and the 316 stainless finish looks like it’ll shrug off corrosion for years.

The hex socket drive grips the Allen key perfectly, no wobble or stripping even when I torqued them down tight on my jig. The 316 stainless finish looks clean and feels solid—exactly what I needed for outdoor machinery that sees salt air.

Finally found a hex screw that doesn't strip out under heavy torque—these fully threaded 316 stainless ones held perfectly on a custom jig I built.
