SOS-440-18 | مسامير تثبيت ذاتية القفل من PEM #4-40 | فولاذ مقاوم للصدأ 18-8 (900/عبوة)

The 18-8 stainless steel finish on these #4-40 standoffs feels really solid, definitely a step up from the cheaper plated ones I've used before. The self-clinching feature made mounting a circuit board much quicker than with separate hardware. I'm glad I bought the 900-pack for future projects.

Finally found the exact standoffs I needed for mounting PCBs in a tight enclosure, and these 18-8 stainless steel ones are holding up perfectly after multiple assembly cycles. The self-clinching feature on the #4-40 threads saved me from having to use extra hardware.

These #4-40 standoffs are perfect for mounting boards; the 18-8 stainless steel feels solid and the self-clinching design holds tight without stripping. No issues with threading, and a full 900 pack means I won't run out soon.
