Circular fasteners, typically made of metal, are designed to hold components onto a shaft or within a housing. These elements secure parts in place, preventing axial movement. A common retail source for obtaining these items is a large home improvement chain. For instance, an external version fits into a groove on a shaft, while an internal one secures components within a bore.
The significance of these fasteners lies in their ability to simplify assembly and disassembly processes, reducing manufacturing time and costs. They provide a reliable and durable method for securing parts, ensuring the stability and longevity of various mechanical systems. Historically, they have replaced bulkier fastening methods like threaded retainers or cotter pins in many applications, offering a more streamlined and efficient solution.
