دبابيس زنبركية 1/16 × 1/2 بوصة | مشقوقة | فولاذ (2000 / عبوة)

I keep a box of these steel spring pins on my workbench and they hold up perfectly under vibration—installed some in a jig that sees constant use and nothing has budged.

For the price, it's hard to beat a full box of these — the slotted design seats firmly and hasn't budged under the vibration on my small assembly jig. I've already gone through half the pack on one project alone.

Was worried about the shear load capacity on these tiny pins, but they held perfectly on a vibration-prone assembly I built. The steel finish feels robust and the slotted design made insertion smooth without any binding.
