Maytronics Dolphin C6 M4x14 pan head machine screw DIN 7985

This is the genuine Maytronics replacement M4x14 pan head machine screw, manufactured to DIN 7985 specification, for use in the Dolphin C6 robotic pool cleaner. It is a Phillips-drive, fully threaded metric fastener designed to secure internal and external panels, covers, and structural components of the robot during assembly and servicing.

Screw specification and design

Conforming to DIN 7985 (ISO 7045 equivalent), this screw features an M4 metric thread with a 0.7 mm coarse pitch and a 14 mm shank length measured from under the head. The pan head profile — cylindrical sides, slightly rounded top, and flat bearing surface — distributes clamping load evenly across the fastening face, reducing the risk of damage to the robot’s plastic housings. The Phillips cross-recess drive allows controlled torque application and minimises cam-out when using a PH2 screwdriver bit.

Application in the Dolphin C6

This screw is a Maytronics factory-specified fastener for the Dolphin C6 robotic pool cleaner. It is used at multiple assembly points throughout the robot — including casing panels, brush cartridge frames, and motor-bay covers — wherever an M4 threaded interface is present. Using the correct factory screw ensures thread engagement depth and head seating geometry match Maytronics engineering tolerances exactly.

Mikor kell kicserélni ezt a csavart?

Replace this screw if the thread is stripped or cross-threaded, if the Phillips recess is worn to the point that a driver cannot achieve clean engagement, or if the screw shank is bent or corroded. During any full disassembly of the Dolphin C6 — for impeller cleaning, brush replacement, or motor service — it is good practice to inspect all fasteners and replace any that show signs of wear before reassembly.

Miért érdemes eredeti Maytronics alkatrészt választani?

Aftermarket screws of nominally the same size can vary in thread tolerance class, head-height, and drive-recess depth. A genuine Maytronics DIN 7985 screw is produced to the same specification as the original factory build, guaranteeing correct thread fit in tapped bores, consistent torque characteristics, and full compatibility with Maytronics service procedures for the Dolphin C6.
