1、 Core specification parameters

Model/specification: M3 × 6 cross disc head machine screw (PH cross groove)

Material: Black high-strength stainless steel/carbon steel, surface treated with anti-corrosion blackening/galvanizing, suitable for agricultural high humidity and pesticide corrosion environments

Size: Thread diameter 3mm, length 6mm, disc head diameter approximately 5.8mm, compatible with T40 nozzle lower cover special countersunk hole

Quantity: Each nozzle comes standard with 4 nozzles under the cover, and the T40 dual nozzle machine has a total of 8 nozzles

Accessory number: Original corresponding to DJI accessory system, compatible with T20P, incompatible with T50

2、 Structural and functional positioning

Tightening core: The cross groove is compatible with a 2.5mm cross screwdriver, which precisely locks the lower cover and main body of the nozzle to prevent the lower cover from loosening or shifting, ensuring the concentricity of the centrifugal disc rotation and the uniformity of atomization

Sealing and Protection: Cooperate with the lower cover sealing gasket to block the leakage of liquid medicine, prevent mud/impurities from entering, and protect the internal centrifugal valve, motor, and transmission structure

Disassembly and assembly adaptation: Micro lightweight design, without increasing nozzle load; The cross groove facilitates quick disassembly and maintenance in the field, and is suitable for high-frequency operation scenarios of crop protection machines
