Key Features
- Specified Dimensional Tolerances — Manufactured to the exact 1-1/2" OD, 7/8" ID, and 1/8" thickness dimensions, ensuring correct bearing surface coverage and consistent clamping performance.
- Genuine OEM Construction — Built to the same material grade and flatness standard as the original, so load is distributed evenly across fastened surfaces without deformation.
- Direct Drop-In Fit for IDX1 — Engineered specifically for IDX1 equipment; installs in the same position as the factory washer with no adjustment or rework required.
- Protects Mating Surfaces — Correct washer thickness and outer diameter prevent fastener heads from pulling through or bearing surfaces from galling under torque.
- Genuine Multiquip Part — Supplied as part number 4E1861900 under the Multiquip OEM parts program, ensuring traceability and confidence in specification accuracy.
A washer serves as a load-spreading interface between a fastener head or nut and the surface being clamped. By distributing the clamping force over a wider area, it prevents the fastener from embedding into or damaging the mating surface and helps maintain consistent preload over time. When a washer is missing, undersized, or deformed, fastener joints can loosen prematurely, leading to vibration-related failures or damage to housings and mounting surfaces on the equipment.
