مسامير عربة مقاس 1/2-13 × 6 بوصات | ملولبة بالكامل | فولاذ عادي درجة A307 (20/عبوة)

Installed these on a pergola project and the 6-inch length gave plenty of bite into the beams. The square neck seated perfectly into the wood, keeping the bolts from spinning while I tightened the nuts.

The square neck on these bolts grabbed the wood perfectly, no spinning during installation. I used them to attach a heavy workbench leg, and the 6-inch length was just right for a solid connection. Plain steel is fine for indoor projects, and the full threading gave plenty of grip.

The square neck under the head bites into the wood just as it should, so I didn't need a wrench to keep them from spinning while I drove them into the deck frame. All 20 bolts came with clean threads and a consistent zinc-free plain finish, and they seated flush without any burrs.
