Machine Key 25 mm Square End

This machine key measures 25 mm in length with a 5 mm square cross-section. It is designed to secure rotating components such as gears or pulleys to a shaft. The square end profile provides a positive drive connection in keyways. Suitable for general mechanical assembly and maintenance tasks.

For Shaft Keyway Repairs

Mechanics and technicians fitting or replacing keys in standard square keyways will find this part matches the 5 mm dimension. Buyers needing rectangular, Woodruff or taper keys should look at other listings. The single key supplied covers one keyway only, so multiple units are required for several shafts.

5 mm Square Section Decides Fit

The 5 mm square dimension is the critical specification that determines whether this key fits your keyway. Verify the keyway width and depth before ordering. Part number 32384 identifies this exact size from Midwest Fastener Corp.
