مسامير نقل #3 × 3-1/2" | فولاذ مطلي بالزنك (200 / عبوة)

The square neck on these #3 carriage bolts grabbed the wood immediately, no spinning while I tightened them. The zinc plating looks clean and even across all 200 pieces, and they drove in straight for my whole framing project.

Put these on a wooden gate frame and the square neck grabbed perfectly in the pilot hole, no spinning. The zinc coating looks clean and should hold up fine outdoors.

Used these to bolt down some metal brackets for a workbench frame and the zinc coating looks clean after a week in a damp garage. The threads caught smoothly and the dome heads give a nice finished look.
