9729-SS-0440-7 | فواصل سويج أوماتوم #4-40 | ستانلس ستيل (600 / عبوة)

The #4-40 threads cut cleanly into the standoffs, and the stainless steel feels solid without being brittle. Packed 600 to a bag, so I have plenty for spacing boards across multiple builds.

Installed a batch of these on a new control panel and they seated perfectly into the aluminum chassis. The stainless steel threads cut cleanly without galling, which I’ve had trouble with on cheaper standoffs.

These are my go-to for PCB mounting now. The swage action seats them firmly in the panel, and the stainless steel threading holds up well to repeated screw insertions. Having 600 in one pack means I’m set for a good while.
