Vol.2 Explaining the Vocabulary of Screws
Dealing with screws involves a lot of specialized terminology. When you're looking up every word you don't know in reference books or on the Internet, the time gets away from you before you know it... . Nedzigon is here to help you out with a few of the most common screw-related specialized terms.
Vol.7 Screw Tightening Control Methods
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.
