What is one main advantage of using Hi-Lok type fasteners?

The main advantage of using Hi-Lok type fasteners is that they can be installed with ordinary hand tools. This accessibility simplifies the installation process, making it easier for technicians to use them in various applications without the need for specialized or expensive equipment. This attribute is particularly beneficial in aircraft maintenance and assembly, as it can reduce labor costs and streamline procedures.

Hi-Lok fasteners are designed to provide the reliability of a threaded fastener while enhancing ease of use. They offer consistent performance in high-stress environments, which is vital for aircraft components. The option highlighting the need for specialized installation tools, while applicable to some fasteners, does not represent an advantage of Hi-Loks. The weight factor may also be a consideration in fastener selection, but Hi-Loks are not specifically designed to be lighter than traditional fasteners. Lastly, while cost can vary, the primary focus of Hi-Lok fasteners is on their practicality and performance rather than being more expensive compared to previous generations.
