Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas ★★★★★

Used a few of these to space a small control board off the chassis, and the aluminum feels solid without adding too much weight. The threads were clean and caught easily with no cross-threading.

Thomas W. ★★★★★

I needed something sturdy for mounting a panel in a tight spot, and these aluminum standoffs fit perfectly—the 1/2" length gave me just the right clearance. The #4-40 threads engaged smoothly with no cross-threading issues, which was a relief.

Chloe ★★★★★

The threads on these #4-40 standoffs are clean and consistent, so my circuit boards sit perfectly level. They're rigid enough for panel mounting, and the half-inch length gives me just the right gap for airflow.
