I needed these for a precision milling setup, and every single pin in the pack held the exact same tolerance. The alloy steel feels really tough and durable, much better than the cheaper carbon steel ones I’ve used before.

The pins fit perfectly into our jig’s reamed holes, making assembly alignment a breeze. I had to check the hardness with a file, and they barely marked—solid alloy steel.

The matte finish on these pins is consistent across all 100 pieces, making assembly much smoother than with standard hardware. They're holding my jig alignment perfectly after a dozen uses without any wear.
