Key Features
- Genuine OEM Tooth Engagement: — Inward-facing serrations bite into the fastener bearing surface, delivering the locking force required by the original assembly design.
- Exact 1-1/8" Bore Sizing: — Matched to the correct bolt diameter used in SG1400C4F and SG1600C4F assemblies, seating flush without shimming or adjustment.
- Confirmed Generator Fitment: — Verified for SG1400C4F and SG1600C4F Multiquip studio generator models, eliminating guesswork when ordering hardware.
- Vibration Resistance: — The internal tooth profile resists rotational loosening under the constant vibration and thermal cycling that generator operation produces, maintaining fastener clamp load over time.
- OEM Material Consistency: — Sourced directly from Multiquip, this washer meets the hardness and surface finish specifications of the original production part, ensuring consistent performance across repeated service intervals.
An internal tooth lock washer works by using a ring of inward-pointing serrations that dig into both the fastener head and the mating surface as the fastener is tightened. This mechanical grip resists loosening caused by vibration, load cycling, and thermal expansion — all conditions common in generator operation. When a lock washer is worn, deformed, or missing, fasteners can back off gradually, leading to loose connections, misaligned components, or electrical and structural failures within the generator assembly.
