Description   The Bernina Needle Threader (Part #033792.71.00) is a semi-automatic needle threader designed for use with various Bernina sewing and embroidery machines. This component facilitates the threading of the needle eye by using a small metal wire to push the thread through, followed by a hook to pull the thread completely through the needle eye . To install, simply remove the existing threader head and snap the new one into place. It’s compatible with Bernina models such as the B125, B135, B145, B150, B153, B155, B160, B163, B180, B185, B200, B210, B220, B230, B240, B430, B435, B440, B630, B640, B730, as well as the newer 4, 5, and 7 Series machines.
