Why You Should Use Skidmore-Wilhelm Devices for Superior Bolting Pre-Installation Verification
The nut and bolt are small parts of your job site, but as anyone who has experienced improperly tightened nuts can attest, they are absolutely integral for a safe and productive facility.
Bolting Pre-Installation Verification Purpose
Bolting is a precise operation that requires the right equipment and tools to ensure that tensions are properly dispersed and bolts can carry necessary loads. It also requires proper preparation. Pre-installation verification is testing your materials in the setting of your job site to discover any issues that your fasteners and tools may encounter.
According to the Research Council on Structural Connections, pre-installation verification is only required when the bolts are to be pre-tensioned. While the manufacturer tests its equipment prior to shipping, these conditions aren’t representative of what your site calls for. It’s necessary to apply real-world testing to ensure that your nuts and bolts will handle the torque tightening application properly.
As the American Institute of Steel Construction notes, there are two points of pre-installation verification:
- Confirm the appropriateness of the fastener assembly (i.e. nut, bolt, lubricant) for pre-tension.
- Confirm that the proper procedure is being used and the bolting crew understand its steps.
Getting Bolt Tensioning Right the First Time
Pre-installation verification might seem cumbersome, but it will improve efficiency. By proving your application method produces properly pre-tensioned and tensioned nuts and bolts, you can carry out the same procedure across the job without needing to reapply or re-inspect later on. And with the right tool, like the Skidmore-Willhelm Model MZ Bolt Tension Calibrator, proof of the correct tightening is on the dial throughout applications.
The Research Council on Structural Connections recommends that a tension measuring device such as the Model MZ be available at every job site.
