The 9810102 hex nut is a direct replacement fastener for SprayTech Airless EP2510 sprayers. It is used in multiple locations including wheel axles, handlebar brackets, and pump mounting points. Manufactured from corrosion-resistant steel with standard threads, this nut provides reliable clamping force to keep components tight during operation. Vibration from the pump and motor can gradually loosen fasteners; replacing worn or missing nuts with this grade 5 equivalent hardware ensures safe operation. The hex shape allows easy installation with standard wrenches. When disassembling the sprayer for maintenance, inspect all nuts for thread damage or distortion. Using a new 9810102 nut during reassembly guarantees proper torque retention and extends the life of mating hardware.
