مسامير عربة 5/8-11 × 18 بوصة | فولاذ عادي درجة A307 (30/عبوة)

The square neck on these bolts gripped the wood perfectly without any spinning, which made installation a breeze. I needed long fasteners for building a heavy play structure, and the 18-inch length gave plenty of bite into the posts.

Used a few of these on a heavy-duty gate hinge project and the square neck grabbed the wood just as it should. Only complaint is a couple bolts had slightly rough threads that needed a little persuasion with a wrench. Still got the job done for a fair price.

Finally got around to using a few of these for a new gate hinge, and the 18-inch length gave me plenty of bite into the post. The square neck seated nicely into the wood without spinning, which saved me a ton of frustration. Only wish the pack came with a few extra washers.
