مسامير عربة مقاس 5/8-11 × 7" | A307 درجة A فولاذ عادي (10/عبوة)

The square neck grabbed perfectly in my trailer frame, no spinning at all while I tightened them down. These 5/8-11 x 7-inch carriage bolts feel solid and the heads sit flush against the wood, exactly what I needed for heavy-duty assembly.

Pulled these into some thick 4x4 posts and the threads grabbed clean without spinning. The plain steel finish isn’t fancy, but for fence work it’s exactly what I needed.

The square neck grabbed the wood instantly on my first test fit—zero spinning even before I torqued anything down. The 7-inch length gave me plenty of thread for the 2x4 sandwich I was bolting together, and the plain steel finish is exactly what I needed for an indoor project.
