This is the forearm screw also called the action slide handle screw. This screw that fits the model 62 and 62A action slide handle (wooden pump forearm). This screw is unique to the model 62, 62A NOTE: Some times the 1890/1906 forearms will be put onto the 62 rifles. That forearm is smaller in diameter and these screws will be too long. If you have a 90/06 forearm on your rifle you will want to use part number wp43.
