براغي رأس سداسي M12-1.75 × 200 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (10 / عبوة)

Used two of these for a structural repair on a boat trailer; the 316 stainless handles saltwater exposure perfectly. The partial threading made alignment much easier than fully threaded bolts would have been.

The threads engaged cleanly on my equipment frame, and the 316 stainless finish already looks better than the old mild steel bolts I replaced. Partial threading gave me just the right grip for that 200mm length without bottoming out.

Used these for a railing repair on my boat and the 316 stainless is holding up perfectly so far against salt spray. The partial threads made it easy to get a solid bite without bottoming out in the blind hole.
