It's important to ensure accurate torque values for metric bolts.

Using, Converting, and Understanding Torque Values for Metric Bolts

You’ve heard the story. In 1999, a navigation error caused the Mars Climate Orbiter to enter the planet’s atmosphere incorrectly, where it burned and shook itself down to microcomponents and molecules. Why? Because information transferred between the spacecraft’s manufacturers and the navigation team was never converted from English units to metric. While it was incorrect…

First Movement Torque Testing

Method for Conducting a First Movement Torque Test

Torque is a critical component in manufacturing many products. Once the assembly process is completed, measuring torque isn’t finished. A threaded fastener should be audited to verify the joint has been tightened to the proper torque specification. Verification ensures compliance to quality requirements. Residual torque is the amount of tension that remains in a joint…
