What is the primary concern with using non-standard fasteners in assembly?

Using non-standard fasteners in assembly raises significant concerns regarding safety and structural integrity. Non-standard fasteners may not adhere to established engineering standards or specifications necessary for ensuring the reliable performance of a structure. These fasteners might vary in strength, thread compatibility, and material properties, leading to unpredictable behavior under load. This compromises the overall safety of the assembly, as it could fail to withstand the forces it is designed to endure.

Additionally, assemblies constructed with non-standard fasteners are more challenging to inspect, maintain, and replace, further increasing the risk of failure over time. Standardized fasteners are specifically designed to meet load requirements and safety regulations, ensuring a reliable connection that can be uniformly expected across various applications. By using non-standard options, there is a real danger of accidents or structural failures, which can have serious consequences for both the integrity of the assembly and the safety of any personnel involved.
