What is a common consequence of using the wrong size fastener for a job?

Using the wrong size fastener for a job commonly leads to fastener failure and safety hazards. When a fastener is either too small or too large for the intended application, it may not provide the necessary strength and security to hold components together effectively. For example, a fastener that is too small can shear under load, while one that is too large may not fit properly within holes or threaded interfaces, causing structural integrity issues.

This failure can result in components coming loose and potentially causing damage or injury. Furthermore, such failures can create unsafe working conditions, especially in critical applications like electrical installations, where components must be securely fastened to prevent malfunctions or accidents. Proper fastener sizing is essential to ensure the reliability and safety of the overall assembly.
