These rods are precision ground and held to a strict straightness tolerance, so they’re ready for turning in a lathe. While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Combine these shafts with a machine key (not included) to transmit torque to gears, sprockets, and other power transmission components. All have an ANSI standard keyway (keys not included; see our selection of key stock). Their edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, or polished to tight diameter and straightness tolerances.
2024 aluminum shafts are lightweight, corrosion resistant, and nonmagnetic. They have a T4 temper, which means they have been heat treated for increased strength.
