Presser Foot Screw (Part #504063). Specifically designed for the Singer 20U series, this high-strength thumb screw is the primary fastener used to lock presser feet onto the presser bar.

In a professional environment, frequent foot changes are common. This industrial-grade replacement features a knurled head for easy manual adjustments and precision threading to ensure your presser foot never shifts during high-speed zig-zag or straight stitching.

Key Features & Benefits
Knurled Easy-Grip Head: Designed with a textured surface for effortless tightening and loosening by hand, reducing the need for a screwdriver during routine foot swaps.

Vibration Resistance: Engineered to stay tight under the rapid mechanical movement of the Singer 20U, preventing the presser foot from vibrating loose and causing needle strikes.

Hardened Steel Construction: Built to withstand the torque and wear of constant use without stripping or bending.

Precision Threading: Manufactured to the exact specifications of the original part to ensure a smooth, secure fit into the presser bar.
