براغي رأس سداسي M10-1.5 X 290mm | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (10 / عبوة)

I needed extra length for a custom bracket, and the 290mm partially threaded design is perfect for that. The hex head grips securely with a socket, and 316 stainless means no rust worries outside.

The 316 stainless steel feels like it will hold up well in the damp marine environment I'm using them in, and the partial threading gave me just the right grip length on my bracket.

Just installed these on a heavy-duty workbench frame and the 316 stainless is noticeably tougher than the standard steel bolts I've used before. The partially threaded section made alignment with the nut much easier during assembly.
