Risks and Prevention of Fastener Overdriving
Overdriving fasteners can lead to stripped threads and weakened joints, making precise torque control essential during the assembly process.
Understanding the application
Excessive tightening can strip threads, damage the drive recess, crush mating material or overload the fastener. Tool power alone cannot determine a safe setting.
Selection & technical considerations
Use the approved tightening method and appropriate tool range. Lubrication and coating changes can alter preload even when applied torque stays the same.
Practical checks before use
If a joint has been overdriven, assess both fastener and mating threads before reuse. Follow the repair specification rather than backing off and assuming recovery.
