2099-440-B-5 | مساند RAF #4-40 | نحاس (200 / عبوة)

The brass threading is clean and consistent across all 200 pieces, so they fit snugly onto my #4-40 screws without any wobble. I’ve used about half of them for mounting a few circuit boards and panels, and they’ve held up perfectly so far.

Ordered these for a small PCB enclosure project and the brass finish looks clean against the board. The #4-40 threading caught immediately on all 200 pieces, no cross-threading or burrs in the batch. Solid value for the price.

These brass standoffs threaded perfectly into my board mounts without any binding, and having a full package of 200 means I won't run out mid-project. The #4-40 threads are cleanly cut and consistent across all pieces.
