مسامير عربة 1/2-13 × 14-1/2 بوصة | فولاذ مجلفن درجة A307 (60/عبوة)

I needed these for a heavy timber frame project and the square neck grabbed perfectly, no spinning when I tightened them. The zinc coating looks clean and they all arrived straight and ready to use.

I've built plenty of decks with carriage bolts and the 14-1/2" length is spot on for thick beams. The zinc plating held up well through a few rainy weeks before I got the framing finished. The smooth heads look clean even when I leave them exposed, and having 60 in one box meant I didn't have to ru

The square neck seated perfectly into the wood without spinning, and the zinc plating looks clean and even across all 60 pieces. Installed a full deck frame with these and didn't have a single stripped thread.
