I purchased a Cobra Class 4 a few months back from a 3rd party and I was just having an issue with the bobbin tension. I removed the bobbin case from the machine to tighten the tension and discovered that there was no bobbin case set screw. Im not sure if it had fallen off prior to having it. Either way I need a new one to put in. Is there any way to get a replacement from a hardware store? I have a lot of orders to process, and I didn't want to have the machine out of service to wait for a new screw to arrive. For the one screw its $21 to have shipped to me.
