دبابيس زنبركية مقاس 1/2" × 3-3/4" | مشقوقة | فولاذ مطلي بالزنك (100 / عبوة)

The zinc plating looks even and clean across all 100 pins, and they drove into my alignment holes without binding or galling. Held a jig together through a full day of vibration without a single pin backing out.

Picked up a pack for a vibration-prone assembly on my workbench, and the zinc plating really holds up without rust after a week of use. The slotted design made installation easy with just a punch and hammer.

I used these to secure a heavy jig on a vibrating table, and the steel zinc plating seems tough enough to handle the constant rattling. The slotted design also made installation straightforward.
