I’m just doing my yearly service changing my hydraulic filters and udt fluid. So the oil has been completely drain. All of my drain plugs didn’t give me any problems except my 1 3/16 plug with magnet on it . For some reason when I put it in to tighten it’s not grabbing the threads. I’m not sure if there’s any tips or tricks to this plug but I thought I’d ask. Other option is to buy another plug , and my last option would be tap and die the hole which i really don’t want to do. Help
