screw for hanging mirror door assembly

Hey there,

Thanks for your post. This closet door roller reminds me of the 23-027 Top Sliding Closet Door Roller. The screw for this roller is not sold separately. 

To confirm that this will work for the repair, carefully look over the specifications. Be sure to double check the diameter of the wheel.
