    Each row is one National Stock Number and the part numbers DLA FLIS lists on it, as written there. A blank means FLIS lists no part in that series on the stock number, not that the size does not exist.

    Reference numbers the Federal Logistics Information System records against the same National Stock Number. A supply-catalog cross-reference, not an engineering-approved interchangeability: confirm against the controlling drawing or spec before substituting. Only equivalents marked cited have a manufacturer or government document, linked with each.
