Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material and dimensional spec of the original M8 lock washer, delivering the correct bite and tension retention required in submersible pump assemblies.
- Drop-In Installation — Matches the original M8 thread pitch and outside diameter, so it seats correctly without modification on any fastener position it was designed for.
- Broad Submersible Pump Coverage — Confirmed fitment across ST4, ST6, ST41230, ST41460, ST61230, and ST61460 Multiquip submersible pump models.
- Maintains Fastener Clamp Load — A functioning lock washer prevents fastener back-off under vibration; a missing or damaged washer can allow critical pump components to work loose during operation.
- Corrosion-Resistant for Wet Environments — Suited for use in submersible applications where exposure to water and moisture is constant, helping fasteners hold their torque over time.
A lock washer is a hardened fastener component placed under a bolt or nut to prevent it from loosening due to vibration or dynamic loads. In submersible pump assemblies, where the unit operates fully submerged and experiences continuous motor vibration, maintaining proper clamp load on all fasteners is critical to keeping the housing sealed and the internal components secure. When a lock washer is worn flat, missing, or incorrect for the application, fasteners can gradually back off, leading to leaks, misalignment, or premature mechanical failure.
