In the aviation industry, maintaining structural integrity across the airframe and every internal system is paramount for achieving safe and efficient flight. Therefore, every fastener, joint, and component of an aircraft must perform impeccably under some of the most extreme operating conditions, making the selection of hardware an essential consideration during design and maintenance stages. Among the many fasteners used in aviation tasks, Hi-Lok and Cherry rivets in particular stand out as industry staples due to their unique designs that promote strong, lightweight connections and ease of handling. In this blog, we will offer an informative overview of Hi-Lok and Cherry rivets, highlighting important elements of their designs, advantages, and role in modern aviation operations.
Aircraft structures are regularly composed of thousands of individual parts that must be joined together to ensure stability and functionality during flight. While there are various ways to assemble items, fasteners are the main means by which these aviation structures are secured, ensuring reliability in the face of expected stresses like vibration, aerodynamic loads, and extreme temperature fluctuations. As such, everything from fuselage panels to engine components are assembled with a range of fasteners, each individual option having its own unique capabilities and applications.
Unlike more conventional hardware fasteners that find ample use in less demanding settings, the components used for aviation purposes must balance several core attributes to be worthy for installation.
Hi-Lok and Cherry rivets both exemplify these basic principles, offering optimized solutions for structural joining applications.
Hi-Lok fasteners are components that serve as a hybrid of rivets and bolts, consisting of a threaded pin and sel-torque-off collar that facilitates installation from a single side of an assembly. As a form of high-strength fastener, Hi-Lok options are widely used throughout wing assemblies, fuselage structures, and control surfaces.
Self-Locking Features: Hi-Lok fasteners consist of a self-locking collar that promotes more secure installation and long-term reliability in the face of stressors.
Cherry rivets are specialized blind fastening systems that are manufactured by Cherry Aerospace, a recognized leader in the production of aerospace fasteners. Unlike conventional rivets that require an operator to have access to both sides of a workpiece for proper installation, Cherry rivets can be completely secured from a single side. This makes them particularly useful in tight or enclosed spaces, driving their popularity throughout the aerospace industry for the initial assembly or maintenance of structures and systems.
Hi-Lok and Cherry rivets both act as useful solutions to address unique fastening challenges in aviation.
Hi-Lok fasteners are generally best for high-strength, load-bearing applications that prioritize weight savings and precision. Oftentimes, one will use these fasteners for:
Cherry rivets, meanwhile, tend to be preferred in maintenance and repair scenarios or when blind installation is necessary. Generally speaking, one will find these fasteners used for:
Whether your individual operations call for Hi-Lok fasteners, Cherry rivets, or other various aerospace hardware, it is always necessary that professionals engaged in procurement ensure product authenticity by working with trusted distributions and suppliers for fulfillment. By selecting components that meet industry standards and originate from reliable manufacturers, operators can maintain both performance and compliance with aviation regulations, avoiding the risks and costly setbacks associated with substandard products.
