Applied Bolting

For 25+ years Applied Bolting has been manufacturing self-indication direct tension indicators, known as DuraSquirt DTIs. We offer three types of DuraSquirt DTIs for the flange market, Target Stress DTi verifies that your torqueing pass actually achieved the proper stud stress. The second is called Single Pass Tightening, in which a #300 and #600 flange can be tightening in a single tightening pass. The SSR DTI is designed for Hot Bolting applications.
