ISO 245:1998 is the International Standard that defines the diameters of lockwire used in the aerospace industry. Published as the second edition in March 1998, it was prepared by ISO/TC 20 (Aircraft and space vehicles), Subcommittee SC 4 (Aerospace fastener systems). The standard is intended for use in the compilation of aerospace product standards and provides dimensional requirements referenced by designers, manufacturers and quality authorities. Dimensions and tolerances in the document are expressed in millimetres and are illustrated in an accompanying figure and table.
Note: ISO 245:1998 focuses specifically on diameters. It does not cover material specification, manufacturing methods, or installation procedures for lockwire.
ISO 245:1998 is directly useful for professionals involved in aerospace fastener selection and documentation:
Practical uses include specifying lockwire sizes on engineering drawings, defining acceptance criteria for incoming inspection, and harmonizing supplier product data to prevent misfits or functional failures.
ISO 245:1998 is part of the body of standards addressing aerospace fastener systems prepared by ISO/TC 20/SC 4. For complete product specifications, it is typically used alongside other aerospace standards covering fastener dimensions, materials, installation practices and quality requirements. When creating or auditing aerospace product documents, reference ISO 245:1998 for diameter requirements and consult related fastener and material standards for full guidance.
