Key Features
- Genuine OEM Specification: — Manufactured to the exact hardness and dimensional tolerances required for M6 fastener applications in submersible pump assemblies, preventing loosening under vibration and load cycles.
- Direct Bolt-On Replacement: — Sized precisely for M6 fastener positions throughout the pump housing and component stack, dropping straight into place during reassembly.
- Broad Submersible Pump Compatibility: — Confirmed fitment across ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models.
- Vibration Resistance: — The lock washer design bites into mating surfaces to resist rotational loosening, helping maintain proper clamp load on pump components operating in wet, high-vibration environments.
- Corrosion-Resistant Construction: — Built to withstand the wet operating conditions inherent to submersible pump service, maintaining fastener integrity even after extended immersion.
A lock washer is a small but critical fastening component that sits between a bolt or nut and the mating surface it clamps against. Its purpose is to resist loosening caused by vibration, torque, and mechanical movement — forces that are constant in pump applications running submerged in water. When a lock washer fails, becomes deformed, or is omitted during reassembly, fasteners can work loose over time, leading to component misalignment, leaks, or structural failure within the pump housing. Using the correct OEM-specified washer for every M6 fastener position ensures the assembly stays properly torqued and sealed through the full service life of the pump.
