William ★★★★★

Decided to switch from metal standoffs to these nylon ones for a circuit board project, and the hex shape made them much easier to grip with a small screwdriver. They threaded cleanly into the #4-40 holes without any binding. Good consistent quality across the whole bag.

James N. ★★★★★

The nylon threads on these #4-40 standoffs are cleaner than I expected—my boards seat perfectly without any cross-threading, and the 5/16" length is just right for a standard stack-up. I ordered one pack for a project and already know I'll be back for more.

Evelyn ★★★★★

I've been swapping out bent metal standoffs on a few old PCBs and these nylon #4-40s thread cleanly without stripping. The 5/16" length sits perfectly under a standard board, and the hex shape gives you a decent grip with a wrench. For a hundred pieces at this price, they're a solid buy.
