9739-A-0440 | مساند ملولبة من نوع Amatom #4-40 | ألومنيوم (100 / عبوة)

The threads on these #4-40 aluminum standoffs are cut cleanly, so screwing them onto circuit boards takes no effort at all. I ordered the 100-pack for a panel-mounting project and every single one seated flush without any burrs or wobble. Exactly what I needed for spacing boards evenly.

Finally, a standoff that actually holds its torque spec after installation. The aluminum is lightweight but the threads cut cleanly with no galling. Perfect for securing a tight PCB stack without stripping.

Pressing these in with my arbor press was effortless, and they seated perfectly flat in the panel — the aluminum feels sturdy enough for holding a PCB in place without being overly heavy.
