براغي ذات رأس مقبس M6-1 × 150 مم | محرك سداسي المقبس | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (50 / عبوة)

Installed these in a marine-grade jig I’m building, and the 316 stainless steel resists saltwater exactly as I hoped. The hex drive seats firmly without stripping, even at full torque.

Finally, a hex socket screw that doesn't strip under torque like the cheaper zinc ones I've used. The 316 stainless threads are clean and consistent across all 50, and the 150mm length is just right for the jig I'm building.

The 150mm length is perfect for reaching through thick flanges on our assembly line, and the 316 stainless finish came out of the box with zero burrs or tool marks. I've torqued a dozen of these to spec and not a single one stripped or deformed.
