Multiquip 29091 Split Lock Washer M10

The Multiquip 29091 Split Lock Washer M10 is a genuine OEM fastening component designed for the MD82 hydraulic ride-on power trowel. Sourced directly through Multiquip's OEM supply chain, this washer is built to the exact material grade and dimensional spec required for correct installation. It is a direct replacement for the original hardware, ensuring proper clamp load and thread retention on the MD82. Keep a few on hand — these small components are often needed during routine maintenance or fastener inspection.

Key Features

• Genuine OEM Hardware Spec — Manufactured to the exact M10 thread pitch, outer diameter, and split angle specified for Multiquip equipment, ensuring correct tension and bite when torqued.
• Drop-In Installation — Matches the original washer position and seating surface on M10 fastener assemblies, so installation requires no rework or shimming.
• Confirmed MD82 Fitment — Verified for the Multiquip MD82 mid-sized hydraulic ride-on power trowel series.
• Vibration Resistance — The split-ring design bites into mating surfaces under torque, resisting fastener loosening caused by the continuous vibration inherent to ride-on trowel operation.
• Critical Fastener Integrity — Used in assemblies where loose fasteners can lead to misalignment or component failure; using the correct washer spec keeps critical connections secure through extended run cycles.

A split lock washer is a deceptively simple but functionally important piece of hardware. Its split ring profile creates a spring-like tension when compressed under a fastener, generating resistance that prevents the bolt or nut from backing out due to vibration or thermal cycling. On a machine like the MD82 ride-on trowel — which operates under sustained vibration from rotating blade assemblies and a hydraulic drive system — fastener integrity across the machine is essential. A missing or worn split lock washer in a critical joint can allow fasteners to loosen progressively, leading to component movement, accelerated wear, or structural misalignment that is far more costly to address than replacing the washer itself.
