4502-440-B | فواصل RAF #4-40 | نحاس (70 / عبوة)

Used these for mounting a prototype PCB and the #4-40 threads were perfectly consistent on every single standoff. The brass material feels solid and should hold up well in the enclosure.

Used a full package mounting a new control panel, and the #4-40 threads caught perfectly in every hole without any binding. The brass looks clean but also feels sturdy enough to hold everything securely in place.

The brass finish looks clean and professional, and the 70-pack gives me plenty of spares for future projects. These #4-40 standoffs threaded smoothly into my circuit board without any binding.
