1636-256-B | فواصل RAF #2-56 | نحاس (5000 / عبوة)

I use these to mount prototype boards and the threading is consistent and smooth on every single one of the 5000 pieces. The brass finish doesn’t tarnish over time, which is exactly what you need for long-lasting panel spacing.

The threads cut cleanly and the brass finish is uniform across all five thousand pieces—no burrs or defects in the batch. I’m using them to stack a few prototype boards and they hold snugly without stripping. Exactly what you’d expect from a bulk pack of standoffs.

These brass standoffs threaded perfectly into my PCB mounting holes without any binding. The 5000-pack is obviously overkill for a hobbyist like me, but the price per unit was too good to pass up for future projects.
