Product Code:SAE J2486
Title:Tension Indicating Washer Tightening Method for Fasteners
Issuing Committee:Fasteners Committee
Scope: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 products before using them with special fasteners or applications.This document defines and illustrates preferred installation and inspection methodologies. The contents of this document are presented as accurately as possible; however, responsibility for its application lies with the user.
