I have fixed two pair of tongs I use for cooking with M3 screws and bolts.

After a few rounds in the dishwasher rust started forming...

Is there any different M3 screws / bolts material that I could find easily that will not rust in dishwasher? Or, if non toxic, an anti-rust paint?


You want stainless steel

That should be readily available in any hardware store that sells metric. Stainless + metric both can be a little bit specialty, so you need that community hardware store that's been around for 100 years, or McMaster-Carr or equivalent in your territory.

  • Stainless and metric is very common in Europe, and that is where the OP is... However, finding Whitworth can be so much more challenging. – Solar Mike Feb 23 '20 at 21:21
  • @SolarMike Tell me about it... I have stuff with 1/2-12 threads... – Harper - Reinstate Monica Feb 23 '20 at 21:24
