مسامير زنبركية 1/8" × 13/16" | مشقوقة | فولاذ مطلي بالزنك (4000 / عبوة)

Needed a solid batch of pins for some heavy vibration-prone assemblies, and these slotted steel ones held everything in place without a single failure across 4000 pieces. The zinc plating is consistent, no rough edges, and they drive in cleanly. Exactly the kind of bulk reliability I was hoping for.

Ran a batch of these through a jig for a vibration-heavy assembly and every single pin seated cleanly without binding. The slotted design really does grip well under shear load—no shifting at all after a few hours of runtime.

The pins slid right into place on my jig and held firm through a full day of heavy vibration. I ordered a full box and every single one has consistent plating with no rough edges.
