The exact moment when a fastener begins to deform permanently under stress. This is when the material starts to stretch and won’t return to its original shape once the load is removed. Unlike yield strength, which is a specific stress value, the yield point refers to the actual onset of this permanent deformation.

The amount of stress a material can handle before it begins to deform permanently. In fasteners, this marks the point where the fastener starts to stretch and won’t return to its original shape after the load is removed.

A yoke end fastener, also known as a clevis end, is a U-shaped metal fitting used to create a secure, pivoting connection between a rod, pipe, or cable and a mounting point.  It consists of a U-shaped yoke with two holes and a threaded shank extending from its base. The yoke end screws onto a rod or cable, and a separate clevis pin is then inserted through the holes of the yoke and the component it's connecting to, like a bracket or another rod. A cotter pin or similar fastener secures the clevis pin in place. This assembly allows the connected part to pivot or swing, making the yoke end a vital component in systems that require controlled motion.

Yoke ends are widely used in a variety of mechanical and hydraulic applications due to their ability to handle significant tensile forces while providing a flexible connection. They are commonly found in hydraulic cylinders, where they connect the piston rod to machinery; in automotive systems, such as steering linkages and suspension components; and in lifting and rigging equipment, where they provide reliable attachment points for cables and ropes. Their simple yet robust design makes them an essential fastener for transmitting force and motion in countless industrial and mechanical systems.
