1/2-13 × 7-1/2 بوصة مسامير عربة | فولاذ عادي A307 درجة A (70/عبوة)

The square neck on these carriage bolts grabbed perfectly in the wood, so they didn't spin while I tightened the nut. For a 70-pack at this length, you can't beat the value for heavy framing work.

These bolts worked great for the heavy timber frame I’m building; the square neck seated firmly in the wood without any spinning during tightening. The 7-1/2 inch length was perfect for the beam connection I needed.

The square neck grabbed perfectly into the pressure-treated lumber without any spinning as I tightened them down. These are solid carriage bolts for the price, and having exactly 70 in the package saved me a second trip to the hardware store.
