They threaded cleanly into the holes on my prototype board with no binding. The aluminum finish looks professional and should hold up well in the final build. Exactly the right length for a standard spacer job.

The aluminum feels surprisingly sturdy for such small standoffs, and the #2-56 threads caught perfectly on my first try. I used them to raise a PCB in a tight enclosure, and the 3/8" length worked out exactly as needed.

These are perfect for mounting smaller PCBs where you need a bit of extra clearance without the weight of steel. I'm glad the threads are clean and consistent across all 100 pieces.
