OPTIMUM FLAT WASHER CONFIGURATION FOR USE WITH DURASQUIRT® AND SQUIRTER® DTIs
Non-standard holes in outer plies must be covered by an appropriate flat washer (see RCSC Table 6.1).
If an ASTM F436 washer is required under a Squirter® or DuraSquirt® DTI, a special flat washer should be procured for optimum squirt performance. While standard ASTM F436 washers are acceptable per specification, their use sacrifices some of the benefits of Squirter® and DuraSquirt® DTIs. See below for details.
