مسامير عربة مقاس 7/16-14 × 5-1/2" | خيط كامل | فولاذ عادي من الدرجة A307 (130 / عبوة)

The square neck under the head grabbed the wood instantly as I cinched them down, and not a single one spun on me across all 130 pieces. The threads are clean and consistent too, which made driving them with a socket a breeze.

These are solidly built bolts for the price; the threads are clean and consistent across all 130 pieces, which saved me a ton of time during assembly. I had to tap a couple of them into some tight pre-drilled holes, but the square neck gripped just right and kept them from spinning.

The square neck on these grabbed the wood right away and didn't spin, which made install way easier than I expected. Heads are clean and the threads are consistent, though a few had light surface rust that wiped off with a cloth.
