Hello! I currently don't have access to this information, but I'll look into it for you ASAP. Please bear with us a little longer. |

Hey there, I think I can help. I checked the screws on the 81-257 roller. The adjustment screw at the bottom of the housing is a pan head machine screw, #1/4-28 x 3/4" long. The upper frame mounting screw would be a #12 pan head sheet metal type screw. However, I'm wondering if you ordered the wrong patio door wheel for your door. That may be why you're having problems. Would it be possible to see a photo of your original roller for us to take a look at an identify? Seeing it side by side with the 81-257 would also help. |

Another idea would be to drill out the adjustment hole in the side edge of the door a little larger to have better access to the adjustment screw. That is what I've done in the past when I ran into the same situation. If all else fails, you could show us a photo of your old rollers out of the door and we can try to find a better match. |
