In this hands-on structural bolting clinic, Applied Bolting Technology™ breaks down proper Direct Tension Indicator (DTI) location and bolt assembly orientation to help installers and inspectors get it right the first time.
You’ll see step-by-step demonstrations of the most common DTI installation methods, including:
- Head-side DTI installation with bumps facing the bolt head
- Nut-side DTI installation when required
- Correct use of hardened flat washers
- Proper snugging and final tensioning procedures
- Two-person installation techniques for safe, accurate bolt tensioning
Most importantly, this video reinforces two critical DTI rules:
1. DTI bumps must always face away from the steel.
2. You can never turn directly against the DTI bumps—always use a hardened washer between the turned element and the DTI.
Whether you’re an ironworker, inspector, engineer, or project manager, this clinic provides real-world guidance to ensure accurate bolt preload, job site safety, and reliable inspection outcomes, especially when using Squirter® DTIs for Visual Verification of Bolt Tension™.
