This is the genuine Maytronics KA50\u00d730 Mtil self-tapping screw used across a wide range of Dolphin robotic pool cleaners to secure housings, panels, brush assemblies and other structural components. With a shank diameter of KA50 (5 mm) and a 30 mm length, it delivers a reliable, corrosion-resistant fastening point wherever it is specified in the cleaner’s assembly. Sourced directly from Maytronics, it is an exact OEM replacement that matches the original in thread form, length and material.<\/p>\n
Self-tapping screws of this type are load-bearing fasteners that anchor key sub-assemblies \u2014 side panels, casing covers, brush holders and drive-train guards \u2014 to the robot’s main chassis. A failed or missing screw of this size can allow panels to flex or detach during operation, creating vibration, uneven cleaning patterns and, in worst cases, ingress of debris into protected zones of the unit.<\/p>\n
This fastener is specified across a broad Dolphin line-up including the Dolphin C6, Deluxe 3, Deluxe 4, Deluxe 5, DLX4, DLX5, DX4, DX6, Dynamic DX6, Edge, Nautilus, Triton, Discovery, Supreme M3, Enduro 21R, 2×2, and Prowler 820 \/ 830 variants. Always cross-reference your robot’s exploded parts diagram to confirm the correct fastener position before ordering.<\/p>\n
Replace this screw if you notice a panel or cover that rattles, lifts or shifts during a cleaning cycle; a stripped or corroded thread that no longer torques down; or a visibly snapped shank discovered during routine maintenance. Because self-tapping screws cannot be re-cut once stripped, a like-for-like OEM replacement is the correct remedy.<\/p>\n
Third-party fasteners that are nominally the same size often differ in thread pitch, case hardness or corrosion-resistant coating, leading to premature strip-out or galvanic corrosion in a permanently wet environment. Genuine Maytronics hardware is manufactured to the precise specification of each robot’s moulded plastic boss, ensuring full thread engagement and the correct clamping force without risk of cracking the housing.<\/p>","protected":false},"excerpt":{"rendered":"
