After two years of work by the TC20/SC4 committee, the new TORX® PARALOBE® ISO standards have been completed and published. Although the standards were created in the aerospace committee, the standards can be readily applied to applications in other industries. 

These new ISO standards follow SAE standards AS8538 and AS8539 that were published in 2019.

The new ISO standards’ titles are as follows:

  • ISO 4579 aerospace - drives, internal, TORX® PARALOBE® drive - geometrical definition, gaging and technical requirements.
  • ISO 4580 aerospace - drives, internal, TORX PARALOBE driver bit - geometrical definition, gaging and technical requirements.
