مسامير عربة 3/4-10 × 18 بوصة | فولاذ عادي درجة A307 (22 / عبوة)

Used these to build a heavy-duty swing set frame, and the square neck under the head kept them from spinning while I tightened them down. The 18-inch length gave me plenty of bite into the pressure-treated beam.

I was a little worried they’d arrive bent or stripped, but all 22 of these are perfectly straight with clean threads. The 18-inch length gives a serious bite, and that square neck really sinks into the wood so they don’t spin while you tighten the nut.

These 18" bolts were perfect for a heavy-duty timber frame project I'm working on. The square neck seated firmly against the wood, so I didn't need a second tool to stop them from spinning while tightening the nut.
