Thanks for reaching out! There are only two types of push nuts we sell and they are typically used for metal bi-fold doors. I cannot guarantee that they will work for your Andersen lock but they may be worth considering as a replacement. Take a look at the 1/4" Push Nut 21-155 and the 5/16" Push Nut 21-156 to see if either of these might work for you. Alternate view with measurements
