Key Features
- Exact OEM Dimensions — Manufactured to the precise ¼" × ¼" × 1-1/2" specification, ensuring full engagement in the keyway with no slop or stress concentration.
- Genuine Multiquip Part — Sourced through authorized Multiquip distribution channels; part number this part matches the original component exactly as it left the factory.
- Broad Masonry Saw Compatibility — Confirmed fitment across MS18E, MS20E, MS18H5.5, MS18H8, MS20H, MS30H, MS30E, and RCC130H models.
- Drive Integrity Under Load — A correctly sized square key transfers torque cleanly between shaft and hub; an undersized or worn key causes slippage, blade wobble, and accelerated keyway damage.
- Drop-In Installation — Standard square profile seats directly into existing keyways on compatible saw models with no machining required.
A square key is a small but critical drive component that sits in matching slots — called keyways — cut into both a rotating shaft and the hub of a component such as a blade arbor pulley or drive sprocket. It locks the two parts together so that rotational force from the engine is transferred cleanly to the cutting assembly. When a square key shears, wears, or works loose, the driven component slips on the shaft, causing erratic blade speed, loss of cutting power, or complete drive failure. Replacing a damaged key promptly with a correctly dimensioned OEM part like the Multiquip 10057-032 prevents secondary damage to the keyway itself, which is far more costly to repair.
