What is the significance of using slotted holes in high-strength bolted connections?

The significance of using slotted holes in high-strength bolted connections primarily relates to their ability to accommodate minor misalignments in structural components. When components are being joined, precise alignment can sometimes be challenging due to tolerances in manufacturing or variations in positioning. Slotted holes provide a degree of flexibility that allows the bolts to be installed without requiring perfect alignment. This characteristic helps to ensure that the connection can still be made securely, even when there are slight discrepancies.

Additionally, the slotted design permits some movement during assembly, making it easier to align parts while putting the connection together. This is particularly important in large structures where small misalignments can occur due to various factors such as thermal expansion, fabrication tolerances, or when connecting multiple components in the field.

While factors like inventory control, ease of adjustment, and inspection may be considerations in the broader context of bolted connections, they do not capture the primary practical advantage of slotted holes, which is centered on their function in dealing with misalignment during the connection process.
