- Verified Part Number Match — Order with confidence: 5000150753 is the correct Wacker Neuson part number for this fastener across all listed PS-series pump configurations.
An acorn nut — also called a cap nut or dome nut — is a fastener with a closed domed top that covers and protects an exposed thread end. On submersible pumps like the Wacker Neuson PS2 and PSA2 series, acorn nuts serve both a mechanical clamping function and a protective role, sealing the bolt end from water, grit, and corrosion that could otherwise compromise the fastener over time. A missing or damaged acorn nut can allow moisture to attack the exposed threads of the mating bolt, making future disassembly difficult and potentially leading to fastener seizure or assembly loosening during pump operation.
