3/16" X 1-1/4" مسامير زنبركية مشقوقة | فولاد (1000 / عبوة)

Finally, a proper pin that doesn't bend when you tap it in. The steel is plenty hard, and the slotted design locks in securely. I've already used a few dozen on a frame jig I'm building, and they're holding tight under vibration.

I needed a bulk quantity for a vibration-heavy assembly, and these steel spring pins held up perfectly under shear load during testing. The 3/16" diameter was exactly as specified, and they drove in cleanly without deforming.

The slotted heads on these spring pins grab really well with a cotter pin, so they stay put even under heavy shear loads. A full box of 1,000 is great for my workbench, and the steel finish handles vibration just fine. Really solid purchase for the price.
