About Steel Key Stock, Zinc Plated, Oversized
The carbon steel key stock has a zinc-plated finish, meets American Society for Testing and Materials International ASTM A108 specifications, and has an oversized tolerance. The carbon steel grade provides a good balance of toughness, strength, and machinability. It is magnetic. The zinc plating provides corrosion resistance and a smooth, reflective appearance. The key stock has an oversized tolerance, which makes it slightly larger than the listed size and provides a tight fit in a keyway. Key stock is used to make a machinery part known as a machine key, which fits into a mating keyway to transmit torque between shafts and hubs or bushings. Rectangular and square key stock shapes are the most common, while step key stock is used for damaged or inconsistent keyways.
