This SAE Recommended Practice covers installation and inspection methods for fasteners which are tensioned using Tension Indicating Washers (TIWs) as a means to ensure that adequate tension is developed in mechanically fastened joints. Figure 1 depicts a typical TIW, and Figure 2 depicts a fastener assembly with a TIW before and after tensioning. This document describes practices for the use of TIWs which are typically produced for use with SAE J429 Grade 5 and Grade 8 fasteners or their metric counterparts, although the same principals hold true for bolted joints using other fasteners. Users are advised to contact a manufacturer for advice on use of these
