window operator screw

I'm afraid I can't tell the size of the shoulder screw you need based on this picture. It may be either our 33-067 or the 33-070. Carefully look over our information for each part to confirm if either can work. We also carry the nylon washers, our 33-206 and 33-207, if you need them. You will need to remove your existing screw from the window to get a better look at it and compare it to the ones we carry.
