Applied Bolting has been manufacturing and testing Direct Tension Indicators (DTIs), est. 1994, to satisfy compression requirements of all applicable specifications and are an acceptable bolt tensioning method by all modern standards. Our DTIs are an integral part of structural steel design that readily illustrates when bolts are properly tightened. EPC firms realize that construction projects can be halted by something as simple as tightening bolts so they require DuraSquirt® DTIs to be used on all slip-critical and pretensioned connections to ensure the structural integrity of their design.
