2111-440-B | فواصل RAF #4-40 | نحاس (100 / عبوة)

I needed some reliable standoffs for a small PCB project, and these brass ones fit the #4-40 threads perfectly without any cross-threading. Noticed the plating is smooth and even, so they should hold up well in a chassis.

The brass threading is clean and consistent across all 100 pieces, and they tighten down without any binding. I used them to stack a couple of PCBs and the spacing came out perfectly even.

Finally found the right size for snugly mounting some smaller PCBs — these #4-40 standoffs in brass fit perfectly and don't strip when you thread them. The hundred-pack means I won't run out mid-project.
