مسامير عربة 3/8-16 × 7" | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (25/عبوة)

Installed these on a dock gate last weekend and the square neck kept them from spinning when I tightened the nut. The 316 stainless seems like it'll hold up way better than the zinc-coated ones I used before.

I needed a longer bolt for a marine railing repair, and these 7-inch 316 stainless carriage bolts are perfect. The smooth, rounded head looks great against the wood, and the partial threading made installation simple.

The square neck under the head grabbed the wood instantly, so I didn't need a second wrench to hold them still while tightening. The 316 stainless finish looks clean and should handle the outdoor deck project without any rust worries.
