How is torque applied to ASTM A193 b8c bolts and why is it important?

Torque application on ASTM A193 b8c bolts in used to obtain the desired tension in the bolt. This tension is the pressure or force exerted to the bolts to form a clamping force between the joint parts which holds the connected parts together and prevents the connected parts from relative motion.

Torque application is very important to provide the connected bolts or bolted joints with sufficient clamping force to prevent bolt joint failure.
Torque application prevents over tightening and loosening in ASTM A193 Grade b8c anchor bolts
