Machine Key Stock

Cut this square or rectangular key stock to length to create a straight machine key. Straight keys are the most common type of key. Machine keys are often the same material and as hard or harder than the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.

Steel key stock is an economical choice with good strength. 4140 alloy steel key stock has greater strength and toughness after hardening than carbon steel, making it useful for high-stress applications. Zinc-plated steel key stock resists corrosion in wet environments.

Slightly larger than the size listed in the table, oversized stock fits tightly in a keyway. Press it into place for use in high-torque applications or to replace a key in a worn keyway. Slightly smaller than the size listed in the table, undersized stock is the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use it when parts need to be taken apart frequently, such as for maintenance or prototyping.

Key stock that meets DIN 6880 conforms to DIN standards for undersized keys.

Machine Keys

Steel keys offer good strength.

Slightly smaller than the size listed in the table, undersized keys are the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use them when parts need to be taken apart frequently, such as for maintenance or prototyping.

For technical drawings and 3-D models, click on a part number.
