Tension Indicating Washer Tightening Method for Fasteners(STABILIZED Apr 2018)
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 recommended practice contains technology and procedures which are mature and not likely to change in the foreseeable future. Current practices in building construction related to the performance of fasteners in structural steel joints can be found in Specification for Structural Joints Using High-Strength Bolts, approved by the Research Council on Structural Connections.
