Bent Garage Door Shaft Key – 1/4" x 1/4" x 3"

This bent shaft key is designed for compatible garage door torsion shafts, sprockets, couplers, cable drums, and other keyed mechanical components requiring a 1/4" square shaft key.

The 3-inch length provides secure engagement between the shaft and keyed component, while the bent end gives technicians an easier gripping point for installation, positioning, and removal during service.

How a Shaft Key Works

A shaft key fits into matching keyways in both the shaft and the component mounted on the shaft.

This mechanical connection allows torque to transfer between the two components while helping prevent the sprocket, coupler, drum, or other keyed part from rotating independently around the shaft.

Why Use a Bent Shaft Key?

The angled end gives installers a convenient gripping point, making the key easier to handle when working around shafts, bearings, sprockets, and other closely spaced hardware.

It can also make removal easier during future service compared with a completely straight key.

Compatibility

Before ordering, verify:

• Shaft keyway width

• Component keyway width

• Required key length

• Available clearance

This shaft key is designed for compatible 1/4" keyways.

Do not force an oversized key into a worn, damaged, or incorrectly sized keyway.

Important Installation Note

Disconnect operator power and properly secure the garage door before servicing torsion shafts, sprockets, cable drums, or other rotating components.

Inspect both the shaft keyway and the mating component for damage or excessive wear before installing a replacement key.
