Learn how to properly perform Pre-Installation Verification (PIV) testing for DTIs (Direct Tension Indicators) in accordance with AISC/RCSC sections 7, 8, and 9. In this demonstration, VP of Sales and Technical Support Rob Westover walks through each step, from snug-tightening to final inspection, showing how to confirm your bolt assemblies achieve the correct tension before installation.
This video covers:
Proper setup for PIV testing using a Skidmore or hydraulic load cell
How to achieve a snug-tight condition and apply final tension
Correct use of a feeler gauge for DTI inspection
Key criteria for passing or failing a PIV test
Why performing PIV ensures safer, more reliable bolted connections
Whether you’re an engineer, inspector, or ironworker, this guide will help you verify bolt tensioning accuracy and meet project specifications with confidence.
