KNUCKLE PIN Meaning and
Definition
-
Knuckle pin refers to a specific type of fastening or connecting pin commonly used in mechanical applications. Also known as a cotter pin or a split pin, a knuckle pin is a slender, cylindrical metal pin with one end formed into a loop or bent into a curve. This curved or looped end resembles the shape of a human knuckle, giving the pin its name.
Knuckle pins typically feature a split or opening towards the straight end, allowing them to be easily inserted into a hole or through aligned holes in two or more objects. Once inserted, the pin's bent or looped end prevents it from sliding out unintentionally, ensuring a secure connection between the objects being joined.
Knuckle pins are commonly used to secure various components in machinery and mechanical systems. They are often employed to lock bolts, nuts, and other threaded fasteners in place, preventing them from loosening due to vibrations or other external forces. Additionally, they are utilized in automotive, aerospace, and construction industries to secure linkage assemblies, hinges, joints, and other moving parts.
Made from sturdy materials such as stainless steel, carbon steel, or brass, knuckle pins are designed to withstand substantial loads and offer excellent resistance against corrosion and wear. They are available in various sizes and designs to suit different applications, allowing for easy installation and reliable connections. Additionally, their affordable cost and ease of use contribute to their widespread popularity across different industries.

Etymology of KNUCKLE PIN
The etymology of the word "knuckle pin" is fairly straightforward. It combines two distinct terms: "knuckle" and "pin".1. Knuckle: The word "knuckle" stems from the Old English word "cnucel" or "cnoca", which referred to a joint of a finger. Over time, it has come to specifically denote the rounded protrusion formed by the bones of a finger when the hand is clenched into a fist. Thus, "knuckle" is now associated with the joints in the fingers or even similar rounded projections on other parts of the body.2. Pin: "Pin" has its roots in the Middle English word "pinne" or "pine". Originally, it referred to a peg or a pointed object used to fasten or secure something. This can be seen in the common use of "pin" for various objects like sewing pins, push pins, or safety pins.
