مسامير عربة 5/16-18 × 1-1/2" | ملولبة بالكامل | ستانلس ستيل 316 (100 / عبوة)

The square neck on these carriage bolts grabbed perfectly into the pressure-treated wood, and the 316 stainless finish feels like it will hold up to coastal weather without rusting.

Installed a deck railing this weekend and these fully threaded 316 bolts didn’t spin a single time once I torqued them down. The square neck seats perfectly, and the stainless finish already looks better than the galvanized ones I used last year.

The square neck on these grabbed the wood perfectly on my dock repair, no slipping or spinning. The 316 stainless feels heavy-duty and should hold up to the saltwater.
