Lystaii 320Pcs M3 Nylon Hex Spacer Standoff Kit Male Female Screw Nut Threaded Pillar Pcb Motherboard Circuit Board Standoffs Mounting Hardware Assortment (Black)

This kit has been awesome for most of my projects. I saw most because I would recommend metal stand for any heavy, or high use, scenarios. For smaller, lighter, electrical configurations such as raising, stacking or connecting PCB boards and components these are perfect and have a great variation of sizes to pick from.

This Lystaii assortment of M3 nylon standoffs and hardware is a handy kit for prototyping electronics and lightweight 3D printer assemblies. The variety provided allows for flexible spacing and mounting of PCBs and light enclosures. In practice, while the spacers thread cleanly and the assortment is well-organized, the inherent weakness of nylon material limits its use strictly to low-load environments. I encountered thread stripping during hand-tightening beyond modest torque levels, which is a known risk when dealing with plastic threads. This makes them unsuitable for anything that involves heat, vibration, or mechanical stress. Therefore, while this kit provides great value for prototyping or educational use, I cannot recommend it for any final or structural assemblies. Hobbyists and students will find it functional, but serious projects demand aluminum or brass alternatives.

Don't expect to much from these, they are cheap plastic. If like me, that's exactly what you needed, then this is the set you want.

Nylon's perfect for electronics/robot projects. Found a lot of use for a large variety of these little bits.

I used these in a portable Meshtastic LoRa node. No issues, worked as described. Product was delivered on-time. Would recommend.
