    Rounded Machine Keys

    Image of Product. Front orientation. Machine Keys. Rounded Machine Keys.
    When installed, these keys fill oval keyways completely, reducing stress on the key and shaft. Using them in a closed keyway keeps them from sliding along the shaft axis. The rounded ends make it easy to slide gears, hubs, and other components into place. These are also known as feather keys. Machine keys are often the same material as 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.
    1008-1045 Carbon Steel—Steel keys are strong and easy to machine. Since steel is the most common material, these keys work in many applications. Steel keys rust when exposed to moisture, so they should only be used in dry environments.
    Zinc-Plated 1008-1045 Carbon Steel— Zinc-plated steel keys resist corrosion in wet environments.
    Oversized Tolerance—Slightly larger than the size listed in the table, oversized keys fit tightly in a keyway. Press them into place for use in high-torque applications or to replace a key in a worn keyway.
    Undersized Tolerance—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. Undersized metric keys meet DIN 6885 dimensional standards.
    ASME B17.1 Class 1 and ASME B17.1 Class 2—Keys that meet ASME B17.1 specifications conform to ASME standards for dimensions and tolerances.

    Machine Keys

    Image of Product. Front orientation. Machine Keys. Machine Keys.
    Straight keys, with a square or rectangular cross section, are the most common type of key. Install them in keyways to transmit torque from shafts to gears and other components. Machine keys are often the same material as 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.

    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 as 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.

    400 Nickel
    Image of Product. Front orientation. Machine Key Stock. Machine Key Stock.
    400 nickel key stock is the most corrosion resistant key stock in our offering and can be used in highly corrosive environments, such as those involving salt water, sulfuric acid, and alkalies. For complete corrosion resistance, 400 nickel keys are typically used with 400 nickel machine parts. Comparable to Monel, 400 nickel is also known for its strength and weldability.

    Tapered Gib Keys

    Image of Attribute. Front orientation. Contains Annotated. Tapered Gib Keys.
    These keys have a tapered body that wedges in to the keyway for a more secure fit than standard machine keys. The gib head makes these keys easy to remove when parts need to be taken apart frequently, such as for maintenance or prototyping. Keys are tapered along their length. Use them to connect gears and other components with tapered keyways to shafts. Keys are made of steel.
    Inch—The height of inch keys decreases by 1/8" for every 12" of length. They conform to ASME B17.1 Class 1 standards for dimensions and tolerances.

    Tapped Rounded Machine Keys

    Image of Product. Front orientation. Machine Keys. Tapped Rounded Machine Keys.
    Thread a screw through the tapped hole to pop these keys out of a keyway. When installed, they fill oval keyways completely, reducing stress on the key and shaft. Using them in a closed keyway keeps them from sliding along the shaft axis. The rounded ends make it easy to slide gears, hubs, and other components into place. To install, press them in to place. Use them for permanent or high-torque applications, or to replace a key in a worn keyway. Keys are made of steel.

    Side View

    Woodruff keys work well near shaft shoulders, where a standard open keyway would create too much stress. They are also often used on tapered shafts. These keys have a rounded shape that makes them easy to remove when parts need to be taken apart frequently, such as for maintenance or prototyping. Because they're usually shorter than standard machine keys, they work best in light duty applications. Use them to connect gears and other components to shafts. Also known as half moon keys.
