HEX M-F M3 x 6 11mm 尼龍支柱 - 50 入裝

The threads are clean and cut perfectly, so every pillar screwed on without any wobble. Fifty pieces in the bag means I’ve got plenty of spares for future builds, and the nylon feels plenty sturdy for light mounting work.

Used these to secure a custom PCB in my 3D printed project, and the 11mm height was exactly what I needed. The nylon material makes them perfect for avoiding any shorts, and the male-to-female design kept everything neatly stacked.

Finally got around to using these for a small electronics project—the 11mm length was perfect for insulating a terminal block, and the nylon feels much sturdier than I expected.
