مسامير عربة 5/16-18 × 5 بوصة | ملولبة بالكامل | ستانلس ستيل 316 (50/عبوة)

Used these to bolt a heavy gate frame together outdoors, and the 316 stainless is exactly why I picked them over standard zinc. The fully threaded length gave me plenty of bite through the wood and into the steel bracket, and not a single one stripped during install. They're secure and rust-free so

The square neck grabbed into the wood immediately on my fence repair, so I didn’t have to wrestle a wrench to keep them from spinning. The 316 stainless finish looks clean and these 5-inchers have plenty of bite for thick posts.

Used these for a dock repair and the fully threaded shaft made it easy to get the right depth in the wood. The 316 stainless finish is holding up great against the saltwater spray.
