Although fastening objects using the axial force generated from tightening is the main role of screws (bolts), in actual work, I think there are many people who control the torque by tightening with a torque wrench, because it is difficult to directly monitor the axial force, and so guarantee the axial force that way. However, there are other methods of control for tightening screws (bolts). These include those with only slightly greater axial force variation than with a torque wrench. Today, Nedzigon will tell you all about them.

Vol. 13 Explaining the Rust Source "Galvanic Corrosion"

Have you ever been surprised by rust suddenly appearing on rust-resistant aluminum?
If this happens, the reduced strength resulting from the corrosion brings fears of possible damage.
This phenomenon is known as "galvanic corrosion". Today, I will explain this principle and how it can be handled.
