A screw helps hold compatible cleaner assemblies together, and this Maytronics Dolphin KA version is a 50 by 30 mm fastener using the 3305030-A reference. Correct fastener size matters because longer connection points need the proper hardware to maintain secure fit without damaging the assembly.

This part has practical value because using the original-style Maytronics screw helps preserve correct thread engagement and structural support. A properly selected replacement contributes to more accurate reassembly and reduces the chance of fit issues caused by substitute hardware.

This type of part is especially useful during rebuild or maintenance work when a longer original screw has been lost, damaged, or stripped beyond reuse. That helps keep the service work complete and correctly matched to the cleaner platform.

Installed in the proper application, this screw helps support cleaner assembly integrity and more dependable overall repair quality.

  • KA 50 x 30 mm screw for compatible Maytronics Dolphin cleaner applications
  • Helps secure cleaner components at longer fastening points
  • Useful when replacing a missing or damaged original screw
  • Supports correct hardware fit and retention
  • Improves repair precision and assembly confidence
