Square Keystock, 1/4"

Square Keystock, 1/4"

The 1/4" Square Keystock is a precision-machined steel key designed to secure rotating components such as gears, pulleys, and sprockets to a shaft. By fitting into matching keyways in both the shaft and the component hub, this keystock prevents slipping and ensures reliable power transmission in mechanical systems. Simple, strong, and dependable, it’s one of those small pieces of hardware that quietly keeps machinery running smoothly—because when shafts spin, it’s nice when the parts attached to them spin too.
