Please take a look at completely updated information to Direct Tension Indicators (DTIs) to be applied on high-strength structural bolting assemblies for preloading as described by EN 14399, ASTM F959/F959M or BS 7644. We have just published on our websites! Pay special attention to DuraSquirt® DTI Sigle Pass Flange System providing customers upon assembling significant time-savings (up to 70% faster) as compared to standard sequences of tightening bolts on flange joints.
