Review on 🔩 Honbay 100pcs M3 Square Nuts: Durable 304 Stainless Steel Construction for Incredibly Reliable Fastening by Juice Jali

I bought these as spare parts for a Prusa i3 3D printer. In most places where square nuts are used on the Prusa, there are slots in the plastic parts where you need to insert the nut. These Honbay nuts are significantly thicker than the ones supplied by Prusa so they won't fit without enlarging the hole. This isn't the fault of Honbay nuts, which are perfectly thin nuts, but if your use imposes thickness restrictions, you may have problems with them. Edit: If you want thinner nuts, search for "DIN 562".
