The Multiquip EE52745 Split Lock Washer #10 SST is a genuine OEM fastener component designed for DEFTANK1 and DEFTANK2 MQ Power Fuel and DEF Tank assemblies. As a direct OEM replacement, this stainless steel split lock washer is manufactured to the same specifications as the original hardware installed at the factory, ensuring a secure, vibration-resistant connection right out of the box. Sourced directly through authorized Multiquip supply channels, the part is the correct part to specify when servicing or reassembling fuel and DEF tank hardware on these units.
Key Features
- Stainless Steel Construction — SST material delivers corrosion resistance suited to fuel and DEF tank environments where moisture and chemical exposure are common.
- Split Lock Design — The split profile bites into mating surfaces under torque load, resisting loosening from vibration and mechanical stress during operation.
- Correct #10 Sizing — Sized specifically for #10 fasteners used in DEFTANK1 and DEFTANK2 assemblies, dropping in without modification to existing hardware.
- Genuine OEM Part — Supplied as an original Multiquip component, matching the exact material grade and dimensional tolerances of the production hardware it replaces.
- Fits DEFTANK1 and DEFTANK2 — Confirmed fitment for both MQ Power Fuel and DEF Tank models, making it the right choice for routine maintenance and repair work on these assemblies.
A split lock washer sits between a fastener head or nut and the mating surface to prevent the fastener from backing out under vibration. The split in the washer creates two sharp edges that dig into both surfaces when the fastener is tightened, generating resistance against rotational loosening. On fuel and DEF tank assemblies, where consistent sealing and secure hardware retention directly affect fluid integrity, a worn or missing lock washer can allow fasteners to work loose over time — leading to leaks or component misalignment. Using the correct stainless steel specification ensures the washer holds up against the chemical environment of diesel exhaust fluid without corroding or losing tension.
