The Multiquip 1023 External Tooth Lock Washer #10 is a genuine OEM fastener component used across a wide range of Multiquip and Whiteman equipment, including ride-on power trowels, walk-behind power trowels, vibratory screeds, roller screeds, masonry saws, mixers, and light towers. This small but critical hardware piece is a direct OEM replacement sourced to the original specification, covering models such as HTX44K4, HTX44K5, STX6H, STX55Y6, HHN31V, HTN28K, HDA-SERIES, J-SERIES, B-SERIES, WSHE-A Series, WM120SH, EM120SM, and many more. Because part 1023 appears across so many Multiquip equipment families, verifying your model against the fitment list before ordering is always a smart move. DHS Equipment stocks genuine Multiquip OEM parts so you can get the right component the first time.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original material and dimensional specification, ensuring the washer delivers correct clamping load and tooth engagement for the fastener joint it secures.
- External Tooth Lock Design — The serrated outer teeth bite into the mating surface under torque, resisting loosening from vibration — exactly the condition found on trowel decks, screed frames, and mixer assemblies.
- Broad Cross-Equipment Fitment — A single part number covering ride-on trowels (HTX, STX, HHN, HTN series), walk-behind trowels (J, B, C, HDA series), WSHE vibratory screeds, WRS roller screeds, Whiteman and Essick mixers, masonry saws, and MLT light towers.
- Drop-In Replacement — Sized to #10 fastener spec, this washer installs directly without any modification to existing hardware or mounting points.
- Protects Fastener Integrity Over Time — A failed or missing lock washer allows bolted connections to back out under continuous machine vibration, leading to loose guards, misaligned components, or structural play — replacing worn washers at service intervals prevents these issues.
An external tooth lock washer functions by using its serrated teeth to grip both the bolt head or nut above it and the surface below it, creating mechanical resistance that prevents the fastener from rotating loose under vibration or dynamic loading. On equipment like power trowels and vibratory screeds — which generate constant cyclical forces during operation — maintaining tight fastener connections is essential to keeping guards, panels, and structural members properly secured. A missing or flattened lock washer removes that anti-loosening protection entirely, which can allow critical fasteners to back out gradually and create unsafe or poorly performing machine conditions.
