TECHNICAL QUESTIONS
Explore common questions about the Skidmore Wilhelm HT-4000 system.
The HT-4000 is a computerized bolt tension verification system used to test high-strength structural bolt assemblies. It helps confirm that bolts develop the required pretension before installation, supporting quality assurance and compliance with project specifications.
Rotational Capacity (ROCAP) Testing verifies that a bolt, nut, and washer assembly can develop the required pretension without thread galling, stripping, or other mechanical failure. The test also evaluates the compatibility and lubrication of the assembly.
ROCAP Testing confirms that bolt assemblies are properly lubricated, compatible, and capable of achieving the required clamping force. It helps reduce installation issues and provides confidence that structural connections will perform as designed.adolescens consequuntur.
The HT-4000 directly measures bolt tension during testing and provides accurate, repeatable data for verification and documentation. Computerized reporting supports quality assurance and project recordkeeping.
The HT-4000 is designed for testing high-strength structural bolt assemblies used in structural steel, bridge, transportation, and infrastructure applications. Testing procedures can be performed on both short and long bolt assemblies in accordance with applicable standards.
Yes. The HT-4000 generates computerized test reports that document bolt tension and test results, providing traceable records for inspection, quality control, and specification compliance.
