Customer Reviews (4.6 / 5 · 5 reviews)

Zoe ★★★★★

These standoffs threaded smoothly into my PCB mounting holes without any binding. The aluminum construction makes them noticeably lighter than steel ones I've used before. Perfect fit for the #4-40 hardware in my latest electronics project.

Adam ★★★★★

I needed something sturdy yet lightweight to space a PCB in a tight enclosure, and these aluminum #4-40 x 5/16" standoffs fit perfectly—they’re strong without adding extra weight.

Eli ★★★★★

Finally got around to mounting my custom PCB, and these #4-40 x 5/16" standoffs threaded in cleanly without any binding. The aluminum finish looks neat against the board, and the 100-pack means I have plenty left for future projects.
