// PART-NUMBER EXAMPLES

Read size and length separately

NAS1352C04-9 identifies 4-40 by 9/16 inch. NAS1352N6-16 identifies 3/8-16 by 1 inch. Preserve leading zeroes in the size identifier.

NAS1352C02LB4 retains LB, the locking-patch identifier, and its 1/4-inch nominal length.

// DRAWING REVIEW

Match the required finish and thread form

The selected C and N entries without a finish suffix are passivated. A material match does not resolve locking, coating, thread-form or drawing requirements.
