مسامير عربة مقاس 5/16-18 × 3-3/4" | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (50 / عبوة)

Installed these for a dock repair where saltwater spray is constant, and the 316 stainless finish shows no signs of corrosion after a month. The fully threaded shaft made it easy to cut down to exact length when needed.

The square neck on these really locks into the wood, so I didn't need a second wrench to keep them from spinning while tightening. The 316 stainless finish is smooth and clean, and all 50 arrived with consistent threading.

Finally, bolts that don't strip when I crank them into pressure-treated decking—that square neck pulled right in. The 3-3/4 inch length was perfect for sandwiching a thick ledger board without hitting anything behind it.
