براغي رأس سداسي ثقيلة 1-1/2-6 × 8 بوصة | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (1/عبوة)

Went straight into my equipment frame and the 316 stainless is clearly tougher than the zinc-plated bolts I used before. The partially threaded section gave me a solid bite without having to stack washers to take up slack.

The partially threaded design grabbed perfectly when I torqued it into the equipment frame, and the 316 stainless gives me confidence it won't corrode in the humid shop. These are exactly what I needed for the heavy-duty assembly.

Installed these on a marine dock cleat and the partially threaded shaft gripped perfectly. The hex head took a socket wrench without any stripping.
