Thread Guide Screw (Part #545180). Specifically manufactured for the Singer 20U series, this high-precision fastener is designed to hold your machine's thread guides firmly in place, even under the high-vibration conditions of industrial sewing.

A loose or missing screw can cause thread guides to shift, leading to inconsistent tension, thread snapping, or bird-nesting. This industrial-grade replacement ensures your machine maintains the steady thread flow required for professional-quality stitching.
