Torque-Angle Controlled Screwdriving: Why It Is Critical and How It Works

A bolt's job is not torque, but preload. Why friction makes torque misleading, how the torque-angle signature acts as a "fingerprint," and how this signature turns errors such as cross-threading, missing parts and double tightening into a poka-yoke — the engineering of traceable screwdriving.
