Multiquip 10057-001 3/8" x 2" Steel Key

The Multiquip 10057-001 is a genuine OEM 3/8" x 2" Steel Key designed for a wide range of Multiquip and Whiteman equipment, including MQ600H-series trash pumps, WM63 and WM45 mortar mixers, and MP-series masonry saws. As a direct OEM replacement, this key is manufactured to the exact dimensions required to maintain proper shaft-to-hub engagement across all compatible models. Sourced directly through authorized Multiquip supply channels, it ensures the correct fit the first time without guesswork. Whether you are servicing a mixer, pump, or saw, the 10057-001 keeps critical rotating assemblies locked and running as intended.

Key Features

• Exact OEM Dimensions — Precision-cut to 3/8" x 2" steel spec, ensuring correct keyway engagement and zero slop in the shaft-to-hub connection.
• Genuine Multiquip OEM Part — Sourced directly from Multiquip, this is the same key installed at the factory — no substitutions or dimensional compromises.
• Broad Equipment Compatibility — Fits MQ600H, MQ600HTB, and MQ600HTP trash pumps; WM63 and WM45 Whiteman mortar mixers; and MP-series masonry saws including MP2090HP, MP2050E3, MP1455HP, and more.
• Prevents Shaft Slippage — A correctly fitted key locks rotating components to their shaft, preventing relative movement that causes premature wear on keyways, impellers, and drive hubs.
• Drop-In Replacement — Matches the original key profile so it installs directly into existing keyways without filing, shimming, or modification.

A shaft key is a small but critical component that locks a rotating part — such as a pump impeller, mixer drum drive hub, or saw blade arbor — to its drive shaft. It sits in matching keyway slots cut into both the shaft and the mating component, preventing the two from rotating independently under load. When a key shears, wears down, or goes missing, the driven component slips or stops turning entirely, halting operation and risking damage to the shaft and hub keyways. Replacing a worn or failed key promptly with a correctly sized OEM part protects the surrounding components and restores full power transfer.
