براغي رأس سداسي M12-1.75 × 160 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (10 / عبوة)

Used these to replace some rusted hardware on a marine dock gate, and the 316 stainless is holding up perfectly against the salt spray. The partially threaded shank gave me just enough grip for the thick aluminum frame I was bolting through.

These bolts handled the load on my press fixture without a hint of flex, and the 316 steel is reassuringly corrosion-proof. The partial threading made seating them through the flange a breeze, and the hex heads grabbed the socket cleanly every time.

Installed these on a heavy machinery jig and the 316 stainless is holding up perfectly against the welding splatter nearby. The partially threaded design made alignment much easier than fully threaded bolts.
