This screw will only fit the Singer Featherweight 221 (221-1, 221J, & 221K, etc.) -- it will not fit the Singer 222 or 301.
Double-check your machine to see if it is missing any of the bed cushion screws. Note: They are not needed for the White Singer Featherweight because those cushions are actually quite a bit smaller and glued in. Click here for more information about the White Featherweight.
Screws are priced individually for replacement, so a quantity of 1 will be 1 screw. Bed Cushions are not included but can be purchased here.
