Metric Undersized & Oversized Keystock Bars
Imperial and Metric keystock bars are metallic bars with four sides and either a rectangular or square cross-section. Keystock bars act as keys to help fix different components to a round shaft. The bar fits into precut slots on the shaft or other components such as a sprocket or pulley, allowing the assembly to rotate as one unit.
How To Order Imperial and Metric Keystock Bars by Size
When ordering from an imperial and metric keystock supplier, you will need to understand the tolerances and standards of the bar. The labels for keystock include the named or nominal size.
Imperial and Metric Undersized Keystock Bars
With undersized keystock, the actual size is nominal to less than nominal. These are typically cold drawn fabricated and polished to increase shine. These often work for repairs in field applications and go by several names:
- Bar stock
- Redi-key
- Machine key bar stock
- Negative key stock
Though most follow ANSI specifications, variations in commercial tolerances are possible. Plated parts add a little to the height and width.
Imperial and Metric Oversized Keystock Bars
The actual size of oversize keystock bars is nominal to greater than nominal. This product shares many of the common names as undersize bars, but it can also go by close key stock or plus key stock. It’s popularly known as Mak-A-Key. These are also fabricated from cold-drawn steel and need filing before use in field repair applications.
