Customer Reviews (4.6 / 5 · 5 reviews)

Owen K. ★★★★★

Spacing out a stack of boards took forever with regular standoffs, but these zinc-plated steel ones press in clean and hold tight. The blind threads mean no screw poking through, which is exactly what I needed for a tight chassis.

Joseph U. ★★★★★

These zinc-plated standoffs seated perfectly into my aluminum panels—no distortion, no stripped threads on any of the hundred I installed. The blind clinch design is a lifesaver when you need a clean, flush mount on the back side.

Adam ★★★★★

Used a hundred of these on a recent board assembly, and the blind clinch feature made installation a breeze without damaging the back side. The zinc plating held up perfectly during handling, no signs of corrosion. Great value for a full box of 1000.
