Answer 1

Torque spec is normally determined by the fasteners size, material of the fasteners, and what you’re threading in to. 25% on most fasteners aren’t much until you get into the high torque range (like where 25% might be another 50 ft/lb), threading into a soft metal like aluminum, or working with tiny fasteners.
