Shearpin
A shearpin, also known as a shear pin, is a type of fastener designed to break or shear off at a specific load. This sacrificial element is intentionally weaker than the components it connects, acting as a safety device. When an overload condition occurs, such as a machine jamming or encountering excessive resistance, the shearpin is the first component to fail. This failure prevents damage to more expensive or critical parts of the machinery.
Shearpins are commonly found in agricultural equipment, marine propulsion systems, and various types of industrial machinery.
The design of a shearpin typically involves a pin made of a material with a known shear
