As a direct OEM replacement, part 3019 meets the original engineering specifications set for every machine it serves. Confirmed fitment spans models including WBH-16, WBH-21, AR14H, AR13H, AR13D, V304EH, V305EH, V305EK, LS300, LS400, LS500, LS600, MC12PH, MC64SK, WM45H, WM63H8, WM90SLF, EM70SLF, EM120, C30HDG, and MQ62TDD, among others.

Key Features
- Genuine OEM Flat Washer: Manufactured to the exact material grade and dimensional tolerance specified by Multiquip — ensuring correct load distribution and surface protection on every fastened joint.
- Drop-In Hardware Replacement: Sized at 3/8 inch to seat flush against the fastener head or nut with no reworking of mounting surfaces or hardware stacks required.
- Broad Cross-Equipment Fitment: A single part number covers power buggies (WBH-16, WBH-21, WTB-16), ride-on rollers (AR14H, AR13H, AR13D), walk-behind rollers (V303E, V304EH, V305EH), concrete pumps (LS300, LS400, LS500, LS600, C30HDG series), mixers (WM45H, WM63H8, WM90SLF, EM70SLF, EM120, MC64SK, PRO12), and trash pumps (MQ62TDD).
- Load Distribution Integrity: A correctly sized flat washer spreads clamping force evenly across the mating surface — preventing fastener pull-through, surface gouging, and bolt loosening under vibration. A missing or wrong-sized washer accelerates wear on housing and frame connections.
- Smart Hardware Stock Item: With fitment across this many equipment families, part 3019 is a high-use consumable worth keeping on the shelf — eliminating unnecessary delays during routine assembly, maintenance, or field repairs.
A flat washer sits between a fastener — bolt, screw, or nut — and the surface being clamped, spreading the load over a wider area to protect the material underneath and maintain consistent clamping tension. On construction equipment subject to continuous vibration and heavy use, washers play a critical role in keeping fastened assemblies tight and preventing surface damage that can compromise structural integrity over time. When a washer is missing, undersized, or worn, the fastener bears the full clamping load at a single contact point, which accelerates thread wear, damages housing surfaces, and allows joints to loosen prematurely.
