Just got these aluminum standoffs for mounting a PCB project - the #4-40 threading fits perfectly and the 3/8 inch length is exactly what I needed. The aluminum feels sturdy enough for permanent installations.

Finally found some standoffs with truly smooth, burr-free edges on both ends. These aluminum 4-40s fit perfectly into my PCB mounting holes without any binding. Exactly the right length at 3/8 inch for my project.

The threads are clean and consistent, so these standoffs threaded perfectly into my enclosure holes without any binding. A full 100-pack gives me plenty of extras for future projects.
