These aluminum standoffs are solid and the threads are clean enough that they screw on without any binding. Used them to mount a control panel and they held everything rigid with no flex. Good to have a 50-pack on hand too.

The 1-1/2" length is perfect for my PCB mounting needs, and the aluminum feels sturdy without adding much weight. Tapping them into place was straightforward, and they hold securely. Exactly what I needed for this project.

The hex shape makes them easy to grip with a small wrench, and the aluminum is lightweight yet feels plenty sturdy for mounting my panel. I used an entire pack on a new project and every single one threaded without any issues. A solid, no-fuss solution for spacing boards.
