What is the risk of using incorrect torque specs on critical fasteners?

• A. Improved torque uniformity
• B. Reduced maintenance time
• C. Thread damage, bolt failure, misalignment, potential safety hazards and system failure
• D. No impact on safety

Answer: (C)

Applying the right torque to critical fasteners is about getting the correct preload—the clamping force that holds parts together and distributes load evenly. If torque is too high, threads can be damaged and bolts can yield or fail, and the excessive clamp can distort parts, causing misalignment. If torque is too low, the joint can’t stay tight under vibration, leading to loosening, wear, and potential joint separation. In critical systems, either scenario can lead to safety hazards and even system failure. That combination of thread damage, bolt failure, misalignment, and safety/system hazards is why this option is the best choice. The other statements don’t reflect the real risks: incorrect torque does not improve safety or maintenance time, and it certainly isn’t without safety impact.
