مسامير عربة 5/8-11 × 28 بوصة | فولاذ عادي درجة A307 (30 / عبوة)

The square neck on these grabbed the wood instantly and never spun a millimeter while I torqued them down, which is exactly what you want from a carriage bolt. All 30 arrived with clean threads and no rust spots, and the plain steel finish is fine for my indoor framing project.

Installed these on a heavy-duty gate, and the 28-inch length gave plenty of bite into the post. The plain steel finish is holding up well so far, no rust in the first few weeks.

The square neck grabbed into the wood perfectly on my deck frame, no spinning at all while I tightened the nut. These 28-inch plain steel bolts feel solid and straight, just what I needed for heavy timber connections.
