Multiquip 2955 Lock Washer 7/16 Zinc

The Multiquip 2955 Lock Washer 7/16 Zinc is a genuine OEM fastening component designed for a wide range of Multiquip and Whiteman ride-on power trowels, including the STX, HTX, MD, and HHX series. As a direct OEM replacement, this zinc-plated lock washer meets the original assembly specifications and is sourced directly through authorized Multiquip supply channels. Confirmed fitment includes models such as STX55Y6, STX55J6, STXD6i, STXDF, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTX6H, HTXD6i, HTXG6DF, MD80, MD105, HHXG5, HHXD5, and HHXD5-ES, among others. Having the correct hardware on hand keeps your trowel assembly tight and your machine performing as intended.

Key Features

• Zinc-Plated Corrosion Resistance — The zinc coating protects against rust and oxidation, maintaining clamping integrity even in wet or outdoor jobsite conditions.
• OEM-Specified Hardware — Manufactured to the exact size and temper called out in Multiquip's original assembly, ensuring proper torque retention at the 7/16 fastener position.
• Broad Trowel Compatibility — Fits STX, HTX, MD, and HHX series ride-on power trowels, covering hydrostatic, hybrid, and mechanical trowel platforms across the Multiquip and Whiteman lineup.
• Secure Fastener Locking — The split-ring design bites into mating surfaces to resist loosening under the vibration and rotational forces generated during troweling operations.
• Correct Part for Reassembly Confidence — Using the OEM 2955 washer during service or rebuild ensures bolt joints meet original clamp load requirements rather than relying on mismatched hardware.

A lock washer is a thin, split-ring fastening component placed beneath a bolt or nut to prevent it from backing out under vibration or dynamic load. On ride-on power trowels, where rotating blade assemblies and drive components generate continuous vibration, properly specified lock washers are essential to keeping structural and mechanical fasteners at their intended torque. When a lock washer is omitted, worn, or substituted with an incorrect size, fasteners can loosen progressively during operation, leading to component misalignment, accelerated wear on mating parts, or outright hardware failure.
