مسامير عربة 3/8-16 × 1-1/4 بوصة | فولاذ مطلي بالزنك (250 / عبوة)

The square neck grabbed the wood instantly when I tightened them down, no spinning or stripping even with my impact driver. Zinc coating looks clean and even across all 250, and the threads cut smoothly into the pre-drilled holes. These are the ones I’ll grab first for any framing or deck project fr

Used a full package of these on a heavy-duty workbench frame and every bolt drove in cleanly without the zinc flaking off. The rounded head sits flush against the wood, giving a much cleaner look than standard hex bolts.

The square neck on these carriage bolts grabbed perfectly into the wood beam I was fastening, making installation a breeze. Just the right length for a 2x4, and the zinc coating looks clean and even.
