Linch Pin Details

  • Linch pins may also be used in place of an R-Clip for securing hitch pins.
  • Linch pins are also known as apple keep pins.


Linch pins are precision fasteners used to prevent a wheel or other part from sliding off the axle upon which it is riding.


Linch pins, also commonly termed as quick release pins, employ a locking ring into the pin design that fastens the pin in place, and are commonly found on trailers, making them ideal for use in agricultural or marine industries.
