Joseph F. ★★★★★

I needed exactly 200 for a prototype run, and every single one threads cleanly onto a #4-40 screw without binding. The consistent length across the batch saved me time adjusting each standoff individually.

Andrew ★★★★★

Used a handful so far for mounting a small PCB prototype, and the hex shape made hand-tightening easy without stripping. Solid value for the quantity.

Lucy ★★★★★

The threads cut cleanly on these #4-40 standoffs, so they screw into the panel without any binding. For the price of a 200-pack, this is exactly what I needed for mounting a few circuit boards evenly.
