Purchasing Sphere, owned and operated by ASAP Semiconductor, is an all-inclusive purchasing platform for hard-to-find and in-demand parts SR57 and components pertaining to the civil aviation, defense, aerospace, industrial, and electronic markets. An NSN is a 13-digit numeric code that serves to identify 'standardized material items of supply' as they have been recognized by all NATO countries and the United States Department of Defense. As such, we have an inventory of more than two billion new and obsolete parts, among which is a vast and diverse array of SR57 parts and much more. This includes items such as Screw Machine SR57 from manufacturer General Signal Corp and many more, all of which are available with short lead times and competitive prices. For NSN parts, you won’t find a more inclusive source than Purchasing Sphere.
