Where can the recommended torque value for nuts be found if not specified?

The recommended torque value for nuts can typically be found in AC 43.13-1B, which is a widely recognized advisory circular published by the Federal Aviation Administration (FAA). This document serves as a guide for the maintenance and alteration of aircraft and includes specifications and recommendations for proper installation practices, including torque values for various fasteners. Such guidelines are crucial in ensuring safety and reliability in aviation maintenance.

While manufacturer warranties may provide some information, they do not usually detail technical specifications like torque values. Industry standards documents could offer relevant information, but AC 43.13-1B is specifically tailored to aviation maintenance and is thus a more reliable source for these parameters. Online engineering forums may contain anecdotal advice or user experiences but lack the authoritative and universally accepted standards that AC 43.13-1B provides.
