Screws come in all sizes and shapes for the Singer 221 Featherweight machine and there are dozens of them. Some can be very hard to come by and if you use the wrong one in your beautiful little machine you will strip the threads of worse. To help you in your search of the right screw send me a picture and tell me where it came from. I am very good at knowing the proper screw you are looking for. I have taken apart and put back together over a thousand of these beautiful little machines. Price for screws is standard no matter what size or shape. Each Screw sold seperatly!!!
