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.
Stainless steel key stock is more corrosion resistant than steel key stock. 18-8 stainless steel key stock offers a balance of strength and corrosion resistance. It may be mildly magnetic. 304 stainless steel key stock offers a good balance of strength, corrosion resistance, and machinability. 316/316L stainless steel key stock has the best corrosion resistance of our stainless steel key stock and may be mildly magnetic. 416 stainless steel key stock is stronger than other stainless key stock and can be heat treated for extra strength. It's corrosion resistant and magnetic. 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.

Step Machine Key Stock
When a keyway is damaged, cut a new, wider one. This key stock is stepped to match repaired keyways in shafts or gears. Cut it to length to create the machine key you need. 18-8 stainless steel key stock offers a balance of strength and corrosion resistance. It may be mildly magnetic.
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.

Machine Keys
![](/prerenderstable/mvPRE/contents/gfx/imagecache/988/98870a455p1-b02-digitall@halfx_636935153774461292.png?ver=imagenotfound)
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.
18-8 stainless steel keys offer a balance of strength and corrosion resistance. They may be mildly magnetic.
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. 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.
