Key Stock Carbon Steel Plain (Inch)
Our Carbon Steel Key Stock with a Plain Finish is a precision‑machined mechanical component designed to transmit torque and prevent relative rotation between shafts and mounted components such as gears, pulleys, sprockets, and couplings. Manufactured from high‑quality carbon steel, this key stock provides dependable strength, dimensional accuracy, and consistent fit for power‑transmission applications.
Key stock is typically installed in a keyway machined into both the shaft and the mating hub, creating a positive mechanical connection that distributes load evenly and supports reliable torque transfer. The plain (uncoated) finish preserves the base material properties and is ideal for controlled environments, high‑temperature use, or applications where additional surface treatment will be applied after machining or installation.
Designed for versatility and mechanical reliability, Plain Carbon Steel Key Stock is commonly used in industrial machinery, motors, pumps, gearboxes, conveyors, agricultural equipment, and general power‑transmission assemblies. Carbon steel construction offers good shear strength and machinability, allowing key stock to be cut to precise lengths for custom installations. Available in a wide range of widths and thicknesses, this key stock provides a dependable solution for OEM manufacturing, maintenance, and repair operations requiring accurate torque transfer and long service life.
