This is the genuine Maytronics OEM replacement screw, designation KA50\u00d716 WN1412, specified for the Dolphin C6 robotic pool cleaner. The WN1412 designation identifies it as a Phillips-drive, pan-head thread-forming screw with a 5.0 mm nominal thread diameter and 16 mm length, engineered to fasten key internal and external assemblies securely within the cleaner body.<\/p>\n
This small fastener plays a disproportionately important role: it locks covers, brackets, drive-train housings and other structural panels into precise alignment. A stripped, corroded or missing screw allows components to shift under the vibration and hydrodynamic load of normal operation, leading to accelerated wear of mating parts and potential ingress of pool water into sealed chambers.<\/p>\n
This screw is specified as a primary part for the Maytronics Dolphin C6. The KA50\u00d716 WN1412 designation also appears in the parts lists of a wide range of other Dolphin robotic pool cleaners, including the Dolphin 2×2 Gyro, Dolphin 300i, Dolphin Active 30i, Dolphin Active 10, Dolphin S50, Dolphin Active 20 and the Dolphin Triton PS Plus, confirming it is a widely deployed Maytronics fastener standard across the range.<\/p>\n
The designation decodes as follows: K50 indicates a 5.0 mm nominal thread diameter; \u00d716 is the 16 mm body length; WN1412 is the W\u00fcrth-Norm \/ industry standard for a Phillips-drive pan-head thread-forming screw designed for use in plastics. This geometry ensures reliable thread engagement in polymer housings without pre-tapping, and the pan head provides a broad bearing surface that resists pull-through.<\/p>\n
Non-OEM substitutes frequently differ in thread pitch, case hardening or corrosion-resistant coating, causing them to strip plastic bosses on first assembly or corrode rapidly in chlorinated water. Maytronics manufactures this fastener to its original specifications, guaranteeing correct thread engagement, dimensional accuracy and long-term resistance to pool chemicals, moisture and vibration.<\/p>\n
Replace immediately if the screw head is visibly corroded, the drive recess is rounded out, or the threads no longer hold torque. Loose or missing screws are a common root cause of rattling, cover detachment and premature motor-seal failure \u2014 a \u20ac3 fastener that prevents a far costlier repair.<\/p>","protected":false},"excerpt":{"rendered":"
