مسامير عربة 5/16-18 × 1-1/2 بوصة | ملولبة بالكامل | فولاذ عادي A307 درجة A (200 / عبوة)

Installed these in a new deck project and the square neck grabbed perfectly into the pressure-treated wood, so no spinning as I tightened them. The 200-count pack was enough to finish my railing and have a handful left over for repairs.

The square neck under that smooth rounded head locked right into the wood without any spinning, which made installing all 200 of these a breeze. I grabbed the fully threaded ones for a project where I needed more grip, and they’ve held up fine.

I needed fully threaded bolts for a tight spot where partial threading wouldn't grab, and these worked perfectly. The rounded head sits flush without snagging, and the square neck really does lock into the wood to stop spinning. A solid pack for the price.
