1. Never over torque a Fastener. To over-torque a Fastener can cause it to stretch beyond normal limits causing Fastener breakage, or loosening of Fastener
2. Never under torque Fasteners because it can cause the Fastener to loosen to break

7. When unsure whether a Fastener should be torque to a specification, torque it
8. Do not re-use a Fastener if:
- If it was installed with an impact wrench
- If it could result in a safety risk

Fastener Failure Modes:

• Overloading - Force exceeds Fastener strength, Fastener loosens or shears
• Over-Torque - damaging the threads and deforming the hardware
• Under-Torque - allowing a joint to come loose. It may also allow the joint to flex and thus fail under fatigue.
• Brinelling - caused by poor quality washers, leading to a loss of clamp load and failure of the joint
• Corrosion - caused by the disintegration of an engineered material due to electrochemical oxidation of metals in reaction with an oxidant such as oxygen, this is why Fasteners must be lubricated unless stated by the equipment manufacturer.
