Timothy Z. ★★★★★

The threads on these #4-40 standoffs are clean and uniform, so my circuit boards sit perfectly level without any rocking. A full 100-pack gives me plenty for multiple projects around the shop.

Sebastian K. ★★★★★

Got my box of 100 and they’re perfectly uniform—threads engage cleanly on both ends, which matters when you’re stacking multiple boards. The #4-40 sizing is spot-on for my panel mounts, and the package count is exactly what it says.

Charlotte E. ★★★★★

The threading on these #4-40 standoffs is consistently clean, so they screw in smoothly without any binding. They’re working perfectly for spacing out a small circuit board in a tight panel enclosure.
