براغي رأس سداسي M18-2.5 × 150 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (10 / عبوة)

Installed these on a piece of outdoor equipment exposed to the elements, and the 316 stainless steel is holding up perfectly against the rust. The partial threading made it easy to get a snug fit without fighting the threads the whole way.

Used these on a marine railing repair and the 316 stainless is already holding up perfectly against the salt spray. The hex head gave my socket a solid bite even with a little rust already forming on surrounding hardware.

Finally, a stainless hex bolt that doesn't strip out when I torque it down—the 316 steel feels solid. The partial threading on these M18s made aligning the plate much easier than a fully threaded bolt would have.
