Singer Class 66 Bobbins for Starlet 6606, 201 & 401 & More | #172222

The Singer #172222 is a steel, drop-in metal bobbin built to the Class 66 standard -- the domed, convex-edged profile that distinguishes older Singer oscillating machines from the flat-sided Class 15 system. Metal construction delivers consistent thread tension and resists the flex that plastic bobbins can develop under frequent winding cycles, making this a preferred choice for sewists who run their machines hard or wind bobbins in quantity. The slight dome on the flange face is the visual key to correct fitment: Class 66 bobbins are NOT interchangeable with Class 15, and installing the wrong class causes hook-timing problems, looping, and thread jams. This 10-pack keeps a ready supply on hand so you can switch colors or thread weights without stopping mid-seam. Sold also under alternate numbers 32522 and 172222PS. These metal Class 66 bobbins fit Singer Class 66 machines spanning the vintage 66/99/185/201 generation through the mid-century 300-, 400-, 500-, 600-, and 700-series oscillating mechanicals (~39 Singer models total), plus White models 8600 and 8800. They do not fit Class 15, Class 15J, L-style, or M-style machines -- verify your bobbin class in your machine manual before ordering.
