8169-A-0440 | فواصل مستديرة Amatom #4-40 × 1-1/2" | ألومنيوم (200 / عبوة)

The aluminum finish looks clean and professional on my PCB stack, and the #4-40 threads bit smoothly without any galling. Pack of 200 means I’ve got plenty left over for future builds, and the 1-1/2" length gave me just enough clearance for the components underneath.

Exactly the right length for spacing out a small control board I was building. The aluminum feels sturdy enough for the job without adding too much weight. Nice to have a full package of 200 so I don't run out mid-project.

These #4-40 standoffs fit my PCB mounting holes perfectly and the 1-1/2" length gave just enough clearance. The aluminum feels sturdy enough for the job.
