FSG 53 Hardware and Abrasives

Customers in the Aerospace, Aviation, and Military and Defense business can explore ASAP Semiconductor's expansive inventory of both in-production and obsolete parts through our proprietary website ASAP Aerospace. Our parts are catalogued according to their assigned National Stock Number.

To expedite the procurement process, U.S. Department of Defense put into place a system that individually and permanently identifies the items that it purchases. This system, termed the National Stock Number (NSN), comprises of 13 digits which are broken down into the 2 ensuing identifying subcategories:

1. Federal Supply Classification Group - The first 4 digits of the NSN identifies the Federal Supply Class code (FSCG).

2. National Item Identification Number - The last 9 digits of the NSN identifies the National Item Identification Number (NIIN).

The FSCG and NIIN can be broken down even further into the following classifying subcategories:

Federal Supply Group - The first 2 digits of the FSCG identifies the Federal Supply Group (FSG).

Federal Supply Code - The last 2 digits of the FSCG identifies the Federal Supply Code (FSC).

National Codification Bureau - The first 2 digits of the NIIN identifies the National Codification Bureau (NCB) or NATO country code.

Item Serial Number - The last 7 digits of the NIIN is merely an item serial number that does not follow an assignment pattern.
