Are squirters allowed by the Research Council on Structural Connections (RCSC), AISC, FHWA, and AASHTO?
Yes, since squirters are made to ASTM F959, the specification for generic DTI’s, with the silicone added for the convenience of the bolt installers and inspectors, they are suitable on any project governed by these specification bodies. They are used on steelwork for buildings, bridges, and original equipment applications.
