مسامير عربة 1/2-13 × 6-1/2 بوصة | فولاذ مطلي بالزنك من الدرجة A307 (25 قطعة/عبوة)

The square neck on these grabbed the wood instantly without any spinning, which made installing all 25 bolts a one-person job. Zinc coating looks uniform, so they should hold up fine in the shed where I'm using them.

The threads are clean and consistent, so these drove in straight without any wobble. Plenty of length for sandwiching thick pressure-treated lumber on a deck repair.

The square neck on these grabbed into the wood perfectly, no spinning while I tightened the nut. For the price, getting 25 zinc-plated bolts this size is a solid deal for heavy-duty framing projects.
