A screw helps fasten compatible cleaner components together, and this Maytronics Dolphin KA version is a 40 by 20 mm fastener using the 3354020 reference. Correct replacement hardware matters because even small fastening differences can affect assembly fit, panel retention, or internal component support.

This part has practical value because using the proper Maytronics screw helps preserve original cleaner assembly standards instead of relying on an uncertain hardware substitute. A properly matched replacement supports cleaner reassembly and contributes to a more reliable repair outcome.

This type of part is especially useful when the original screw has been lost, stripped, or damaged during service. That helps restore the intended fastening point while keeping the repair more precise and complete.

Installed in the proper application, this screw helps support cleaner assembly integrity and better overall service quality.

  • KA 40 x 20 mm screw for compatible Maytronics Dolphin cleaner applications
  • Helps secure cleaner components during repair and reassembly
  • Useful when replacing a missing or damaged original fastener
  • Supports correct hardware fit and retention
  • Improves repair precision and service confidence
