Installed these to lift a small PCB off the aluminum case I'm building, and the 1/4" length worked perfectly. The aluminum material feels solid and the finish is clean across all pieces.

Exactly the right size for keeping circuit boards off the chassis—the aluminum feels sturdy and the 1/4" length is spot-on. I used a whole package on a custom enclosure and every spacer threaded cleanly without any snags.

Finally got these for a project where I needed consistent spacing between panels, and the aluminum feels plenty sturdy for the job. They’re exactly 1/4" as listed, which made alignment easy.
