مسامير نقل 5/16-18 × 3/4 بوصة | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (100 / عبوة)

That square neck under the head locked right into the wood as I tightened them, so I didn't need a second wrench to hold anything still. The 316 stainless finish looks clean and should hold up fine in the damp shed where I used them.

The 316 stainless steel is a big win for outdoor projects—I left them exposed to salt air and there's zero rust after a month. Fully threaded meant I didn't have to hunt for shorter ones on my fence repair, and the square neck grabbed the wood solid the first time. Exactly what I needed.

The square neck on these bolts locks right into the wood, making assembly much easier than with standard hex bolts. I used them for a deck repair and the 316 stainless feels solid against the coastal weather.
