I had got an unfinished
"I had got an unfinished piece. The holes where screws connecting to fan blades will go were missing threads to let the screw climb on. Return is a waste of my time. So I went to Home Depot to get drill and tap bit , which creates them screw threads on holes. I used Milwaukee 1/4 -20 UNC and that created the threads on holes. Solved my problem. Adding this here in case anyone runs into this issue"
