Customer Reviews (4.8 / 5 · 5 reviews)

Richard D. ★★★★★

These are the exact right length for my PCB mounting job, and the aluminum is rigid enough that I don't worry about them bending under pressure. The #4-40 threads on every one of the fifty pieces were clean and consistent, so no wasted time re-tapping.

George ★★★★★

Used a full bag mounting panel spacers in a test jig, and every one threaded cleanly onto #4-40 screws with no binding. The aluminum is lightweight but feels sturdy enough for the job.

Isabella ★★★★★

The aluminum finish is clean and consistent on every single piece in the pack, which makes spacing my panel mounts look professional. Threading them onto #4-40 screws was smooth without any cross-threading, and the 1-3/4" length gives just the right gap for airflow between boards.
