مسامير نقل مقاس 1/2-13 × 4-1/2 بوصة | ملولبة بالكامل | درجة A307 فولاذ عادي (130 / عبوة)

I needed a full 4-1/2" length to go through a thick wooden post, and these carriage bolts had plenty of thread to cinch down tight. The square neck grabbed hold instantly without spinning, making installation a breeze.

The square neck under the head digs in just right, so these 4.5-inch bolts stay put without any wrench work on the head. The A307 plain steel finish is exactly what I expected for outdoor framing, and having 130 in one pack means I won’t be running back to the store mid-project. Solid buy all around

The square neck under the head grabbed tight as I tightened them into the wood, so no extra wrench was needed to keep them from spinning. For a full 130-pack, the threading feels clean and consistent across every bolt, making assembly quick and smooth.
