Manufacturer part: 92288A731

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.Zinc-Yellow-Chromate-Plated 1045 Carbon Steel—Zinc-yellow-chromate-plated 1045 carbon steel key stock is an economical choice with good strength and resists corrosion in wet environments.Undersized Tolerance—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.DIN 6880—Key stock that meets DIN 6880 conforms to DIN standards for undersized keys.
