SO-440-6 | فواصل ذاتية التثبيت من PEM #4-40 | فولاذ (100 / عبوة)

Installed these standoffs on a steel chassis for a PCB mount and they seated perfectly with no distortion. The threads ran smooth even after pressing in with an arbor press. Just what I needed for a clean, secure fit.

I needed a reliable way to space my PCB from the chassis, and these steel standoffs pressed in cleanly with zero distortion. The #4-40 threads are crisp and grabbed my screws perfectly.

The clinching action on these was perfectly consistent across all 100 pieces, so every standoff seated flush into the sheet metal without any wobble. The steel threads cut cleanly for my #4-40 screws, and they've held up great under repeated assembly and disassembly of my test panels.
