MIDWEST FASTENER CORP
MIDWEST FASTENER CORP 32391 Machine Key Square End 50 mm 6 mm Sq
Square-end machine key measuring 50 mm long by 6 mm square for securing rotating components
- 50 mm length fits standard keyways
- 6 mm square section provides positive torque transfer
- Square-end design prevents rotation in the slot
- Machine-key profile suits shaft and hub assemblies
- New condition ensures full dimensional accuracy
50 mm Square Machine Key
This 50 mm long machine key features a 6 mm square profile and square-cut ends. It is designed to transmit torque between a shaft and a mounted component such as a gear, pulley or coupling. The steel construction provides the shear strength required for standard power-transmission tasks. Part number 32391 identifies this specific size from Midwest Fastener.
Mechanics assembling keyed shaft connections
The key fits keyways cut to a 6 mm square dimension on both the shaft and the hub. It suits maintenance technicians replacing a sheared key or machiners fitting new rotating elements. Builders needing a rectangular cross-section, a different length, a tapered profile or a Woodruff key will not be able to use this item. The square-end geometry also prevents use in rounded-bottom keyseats.
6 mm square cross-section
The 6 mm square dimension is the single specification that determines whether this key matches the keyway. Both the shaft slot and the hub keyway must be machined to accept a 6 mm square key for the fit to function correctly. If the keyway width or depth differs from this size, the part will not transmit torque as intended. Verify the keyway dimensions before ordering.

Questions about this item
Will the 50 mm length need trimming for standard keyways?
The key is supplied at 50 mm overall length and 6 mm square section; cut it to the required keyway depth with a hacksaw or grinder if the slot is shorter.
What dimension limits torque transmission under continuous load?
The 6 mm square cross-section determines the shear area, so sustained torque is limited by the key material and fit rather than the 50 mm length.
Does the key generate heat or noise during all-day operation?
As a solid steel machine key it has no moving parts, so it produces no noise and negligible heat under normal power-transmission duty.
