Using your Klein Tools 3265 Standard Bull Pin is easy. Just insert it into the appropriate hole or area where you need to secure or mark something. When using, make sure to apply force evenly to avoid any damage to the pin. As for maintenance, keep it clean after each use. You can wipe it down with a dry cloth. Since it has a black rust - resistant finish, it's less likely to rust, but if you notice any signs of rust, you can use a light rust remover. Store it in a dry place to prevent long - term exposure to moisture. And be aware that the standard design doesn't offer extra protection against mushrooming, so use it carefully in high - impact situations.
