MIDWEST FASTENER CORP 32367 Lockout Kit

SKU CH-EMZY-K1NQX

Provides a 3-inch square-end machine key for secure shaft-to-hub connections

  • Square-end design prevents rotation in keyways
  • 3-inch length fits standard lockout applications
  • 1/4-inch square profile matches common machinery slots
  • Durable steel construction resists deformation under load
  • New condition ensures reliable first-use performance

Square-End Machine Key Kit

This 32367 kit from MIDWEST FASTENER supplies a square-end machine key measuring three inches long by one-quarter inch square. It is intended for mechanics and maintenance staff who need to secure rotating components such as gears or pulleys to shafts in automotive or industrial equipment.

Replaces Worn or Lost Keys

The key replaces a damaged, sheared or missing original so the drivetrain regains positive torque transfer without play. The upgrade is worth it when the existing keyway is still within tolerance but the old key has deformed or been lost during disassembly.

Verify Keyway Dimensions First

Confirm that the shaft and hub keyways accept a one-quarter-inch square profile and that the three-inch length matches the assembly before ordering. Buyers needing a different cross-section, a tapered end or a longer key will need a separate part number.

Questions about this item

What keyway width does the 1/4 in square end of the 32367 machine key fit?

The 1/4 in square end fits a standard 1/4 in keyway slot in shafts, hubs or pulleys.

How do you install the 32367 machine key without damaging the keyway?

Align the square end with the keyway, then tap it in gently with a soft-faced mallet until flush; forcing it can burr the slot.

When should the 32367 machine key be replaced?

Replace the key if the square edges show rounding, shear deformation or visible wear that lets the hub rotate on the shaft.
