List of Federal Supply Groups (FSG) and Class (FSC)

Federal Supply Classes (FSCs) are a string of four numbers found at the beginning of an item's designated National Stock Number (NSN). These digits are used to group products into part families specified by the US federal government, and on this page, you can search for specific parts by the FSC that they are categorized in. This Federal Supply Groups (FSG) catalog features a wide range of popular Federal Supply Class (FSC), including FSG 15 Aircraft and Airframe Structural Components, FSG 16 Aircraft Components and Accessories, FSG 20 Ship and Marine Equipment, FSG 25 Vehicular Equipment Components, FSG 26 Tires and Tubes, and many others.

With an inventory of over 2 billion new, used, obsolete, and hard-to-find items, customers have plenty of options to peruse through. More than that, you can trust in the integrity of our stock, as every featured part type has been sourced from leading manufacturers on our Approved Vendor List (AVL). Once you find an item that sparks your interest, simply submit an RFQ form to receive a quote for your comparisons. Upon receiving your request, a dedicated representative will reply with a solution fit to your specific needs within 15 minutes or less!
