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 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.
Acetal plastic and nylon 6/6 plastic key stock are slippery and wear resistant. Acetal resists swelling when exposed to moisture.
PEEK plastic key stock resists chemicals, moisture, and high temperatures. It meets MIL-P-46183 Type 1 specifications for nonreinforced plastic. 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.
