مسامير عربة 1/2-13 × 1-1/4 بوصة | خيط كامل | فولاد عادي درجة A307 (450/عبوة)

The square neck grabbed perfectly into the wood, so I didn't have to hold the bolt while tightening down hardware. For a plain steel fastener at this price point, the threads were surprisingly clean and consistent across all 450 pieces.

Pulling these carriage bolts into the wood for a pergola build was surprisingly easy; that square neck really does lock them in place without any spinning. The entire box of 450 pieces should last me through several projects, and the plain steel finish is exactly what I needed for indoor framing.

Got a whole box of these for a deck project, and the square neck under the head really does lock in tight without spinning. Having 450 in one package saved me a second trip to the store.
