Product Overview
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 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 keys offer good strength.
316 stainless steel keys have excellent corrosion resistance, but aren't as strong as steel keys. They may be mildly magnetic.
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.
Metric keys conform to DIN 6885 standards.
