Q: I’m looking for a nut in a large metric size. I know I can’t get it made in this large a size for class 10 steel so I’m hoping you can recommend a material that can be made to an M16 with similar strength.
A: If you are looking for a lightweight nut that has similar strength properties to a class 10 steel nut you should consider titanium grade 5. Titanium Gr 5 is a high strength grade of titanium that has very similar strength properties to class 10. Additionally the titanium nuts will be roughly 1/2 the weight of the steel nuts.
