Screw, Tap & Tool for Truing Mid-Bed Threads

The Tapping Screw is used to "re-true" or re-tap the threads on the bed, just to the right of the needle plate, of your Singer Featherweight 221. Attachments such as the amoeba-shaped embroidery and darning feed cover plate, buttonholer feed dog coverplate, underbraider, as well as new accessories like our ever-popular Featherweight Accurate Seam Guide are all secured to the bed of the machine via one of these threaded holes. Be sure to watch the video under the video tab.  *You will notice that your screw has been coated with a corrosion preventative so it will be a tad oily.  *This tutorial is for the Singer Featherweight 221 model in original black, white or tan.  It will work for the Featherweight 222 as well, but with the throat plate on a 222 being made of steel (rather than aluminum, like the 221 model), this technique will rarely be necessary.
