Singer Class 15 Household Sewing Machine Metal Bobbin Case

The MH bobbin case is a replacement metal case for Singer Class 15 household sewing machines. It holds the loaded bobbin under the needle plate and seats in the rotary hook, feeding the lower thread up to meet the needle thread as each stitch is formed.

MH machines the case from metal so its tension spring and latch keep a steady, adjustable pull on the lower thread for even stitching. Built as a direct replacement for the Singer Class 15 family, it drops into place to restore worn or lost cases, giving repair shops and home sewers a reliable spare.
