Richard Q. ★★★★★ Oct 23, 2026

The threads cut cleanly and they fit snugly into my PCB mounting holes without any wobble. Solid little standoffs for the price, exactly what I needed for spacing a control board.

Nicholas K. ★★★★★ Oct 22, 2026

These #4-40 standoffs are perfectly machined, every single one has clean threads and a consistent height. I used them to mount a panel in a tight chassis and the spacing came out exactly right. Exactly what I needed for the job.

Amelia ★★★★★ Oct 21, 2026

The threads are perfectly clean, and the finish on these standoffs is exactly what I needed for mounting a small circuit board inside a tight enclosure.
