Machine Key Stock
![](/prerenderstable/mvPRE/contents/gfx/imagecache/988/98830a300p1-b02-digital@halfx_636929185096747334.png?ver=imagenotfound)
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. 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.
