مسامير زنبركية 7/16 × 4 بوصة | مشقوقة | فولاذ مطلي بالزنك (300/عبوة)

Used a batch to secure a pivot arm on a farm trailer, and they held tight even under heavy vibration. The zinc plating kept them rust-free during a week of rain. Exactly the grip I needed for shear load.

Tackled a heavy equipment alignment job and these slotted pins held firm through constant vibration. The steel zinc plating looks like it'll resist rust better than the plain steel ones I used before.

The zinc plating on these 7/16” spring pins feels solid and even, which gave me confidence they’ll hold up under vibration. Installed a few to retain a heavy bracket on my tiller, and they seated tight with no slop. Exactly what I needed for a rugged shear-load application.
