Machine Compatibility
This screw is intended for compatible Yamato sewing machine assemblies where part 20612 / 20612-137 is specified.
The available Yamato parts reference identifies 20612 within Yamato’s parts catalog. However, the exact application can vary according to the machine model and assembly.
For that reason, compatibility with specific models such as DCZ-341, DCZ-361, DCZ-920, FD Series, and AZ Series should be verified against your machine’s parts book or the original screw before purchase.
Likewise, compatibility with Jack, Siruba, Zoje, GEMSY, or Kansai Special machines has not been independently confirmed for this exact part number.

Best Uses
The 20612-137 replacement screw can be useful during routine industrial sewing machine servicing and mechanical repairs.
Typical applications include:
- Overlock machine maintenance
- Interlock machine servicing
- Replacement of a missing fastener

- Machine assembly maintenance
- Sewing machine spare-parts replacement
- Workshop and garment-production machine repairs
However, the screw should only be installed in an assembly where the 20612 / 20612-137 part number is specified or where the replacement has been confirmed to match the original.
Why Correct Screw Matching Matters
Industrial sewing machines operate with precisely aligned mechanical components. As a result, the wrong screw can affect component seating or thread engagement.
Before ordering, compare your existing screw with the replacement. Check the part number, head design, thread, length, and installation position whenever those specifications are available.
