براغي رأس سداسية M12-1.75 × 290 مم | فولاذ مقاوم للصدأ 18/8 | ملولبة جزئيًا (10 / عبوة)

Installed these on a saltwater boat railing where rust is always a problem, and the 18/8 stainless steel shows no signs of corrosion after a month of exposure. The hex head gave a solid, no-slip grip with a socket wrench, and the 290mm length was exactly what I needed for the through-bolt applicatio

Replacing a stripped bolt on my press brake, these 290mm screws threaded in clean with no binding—the 18/8 stainless looks solid and the hex head grabbed the socket perfectly. The partial threading gave me just enough grip for the frame depth without wasting shims.

Used these to mount a heavy-duty conveyor bracket at work. The 18/8 stainless gives me peace of mind against rust in the damp environment, and the partial threading made alignment a lot easier.
