Instructions for Fixing Slipping Hinge Pins on Metal Boxes or Cases

Use these simple directions to adjust a hinge pin that starts to slide out of a metal case or box such as those used for business cards, pills, vitamins, etc.

Typically, the lids and bottoms of metal cases and boxes are held together with a thin brass rod on pin inserted in the hinge slot at the back of the case. If too loose, these pins can start to poke out of one end.

1. Remove the current hinge pin. Partially unbend a paper clip and use the end to insert into one end of the hinge slot to help partially push the pin out, then grasp pin with fingers or a pair of pliers to fully pull out. Sometimes this may be easier to do when the case is open rather than closed because the case may bind in certain positions.

2. Take the hinge pin and put a bend or slight kink in it. This will create tension on the hinge pin when you replace it in the hinge slot. Slide back into hinge slot. The hinge pin should offer resistance. Push end of pink against a hard surface to help push it fully into place.

3. If the pin still slips, add a larger bend to the rod and reinsert.

4. This same process may be used if using to swap out the front or back of a case for another. Follow the same instructions, but remove and exchange lid when pin is removed, wiggling or gently moving each part to help align when reinserting the pin as it may get caught slightly on each section of the hinge slot.
