مسامير عربة مقاس 3/4-10 × 15 بوصة | فولاذ عادي درجة A307 (35/عبوة)

The square neck under the head grabbed perfectly into my pressure-treated beams, and none of them spun while I was tightening. These 15-inch carriage bolts are solid and feel like they’ll hold up well outdoors.

I needed heavy-duty bolts for a timber retaining wall, and the 15-inch length on these was just right. The square neck seated nicely as I tightened them, and all 35 came out of the package with clean threads.

The square neck grabbed perfectly into the treated lumber for my deck project, no spinning at all when tightening. These 15-inch bolts are hefty and feel solid, definitely heavy-duty enough for structural work.
