What is the range of sizes for self-locking fasteners that Running Torque is applicable to?

The range of sizes for which Running Torque is applicable to self-locking fasteners is 5/8'' and smaller. This is due to the specific characteristics and functionality of self-locking fasteners, which typically require a certain range to ensure their locking mechanism works effectively.

Running Torque is a critical factor in the installation process of these fasteners, as it indicates the amount of torque needed to achieve proper locking without stripping the threads or overcoming the locking mechanism. Fasteners that exceed this size, particularly those larger than 5/8'', may not perform optimally under the specified torque conditions, leading to potential failure or improper locking. Thus, it's clear why this size range is critical for executing optimal performance when using self-locking fasteners.
