Key Features
- Genuine OEM Dimensional Accuracy — Machined to the exact 1/4 x 1-1/4 square key specification, ensuring full contact across the keyway for solid torque transfer with no slop or play.
- Drop-In Keyway Fit — Sized to seat directly into the existing shaft and hub keyways on compatible Multiquip Masonry Pro saws without filing or reworking the slot.
- Broad MP Series Compatibility — Confirmed fitment across MP1H, MP115E, MP120E, MP1455HP, MP25E1, MP25E3, MP275E3, MP2H, MP2050E1, MP2050E3, and MP2090HP masonry saw models.
- Torque Transmission Restored — A correctly installed square key locks the blade drive component to the shaft, maintaining consistent blade speed and preventing slippage under load.
- Drive Safety Under Cutting Loads — A worn or sheared key can cause the blade drive to slip unpredictably during cutting; replacing with a genuine 10057-011 restores secure, controlled power delivery.
A square key is a small but mechanically critical component that sits in matched keyways cut into both a rotating shaft and the hub of a drive component — such as a sprocket, pulley, or gear. Its job is to lock those two parts together rotationally so that torque from the engine is transferred reliably to the drive train. When a square key shears, deforms, or works loose, the driven component can slip freely on the shaft, causing loss of blade power or erratic cutting behavior. Replacing a damaged key promptly with the correct Multiquip 10057-011 restores the mechanical connection and protects both the shaft and hub keyways from further wear.
