دبابيس زنبركية 7/16 × 3-1/4 بوصة | مشقوقة | فولاذ مطلي بالزنك (300 / عبوة)

The zinc plating seems durable so far and the slotted design made installation a breeze with just a screwdriver. I needed exactly this size for a machinery alignment project and they held firm under heavy vibration.

Used these to replace worn pins on a heavy tiller attachment, and the zinc plating kept them from binding even after a muddy season. The 7/16" diameter fit perfectly into the factory holes without any filing needed.

The zinc plating on these pins is nice and even, held up well during installation without chipping. They slid right into place and feel sturdy enough to handle vibration in my equipment.
