Hi,

We need to check thread profile of an Orthopedic bone screw on a profile projector .Is there a relevant ISO / ASTM standard for this ?

Also at what magnification should these be observed on a profile projector ...10X , 25X ,50X and why?

Any help would be highly appreciated .

Thanks
michelle
