Assess the Pin: Ensure the pin or key you intend to remove has already been loosened. If the pin is seized or stuck, do not use this pin punch.

Position the Pin Punch: Place the 1/4-inch tip of the Mayhew 71005 pin punch squarely onto the center of the loosened pin or key.
Strike the Punch: Using a hammer, strike the striking end of the pin punch firmly and directly. Apply controlled force to drive the pin through and out of the material.
Remove the Pin: Continue striking until the pin or key is fully driven out and can be safely removed.
