The 304 stainless steel key stock has an unpolished (mill) surface, meets American Society for Testing and Materials International ASTM A479 specifications, and has an undersized tolerance. The 304 stainless steel grade provides good corrosion resistance. It may be slightly magnetic. The key stock has an undersized tolerance, which makes it slightly smaller than the listed size and provides a loose 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.

I cut about an inch off with a hacksaw to create key for the 5 inch, 5/8" arbor top v-belt pulley on a 1987 Craftsman 113.243311 bandsaw perfectly. This key alone was not enough to stop the pulley from wobbling but the key fit the slots perfectly and allowed me to tighten the assembly to the arbor securely. I eliminated the wobble by carefully bending the pulley with a flat blade screwdriver wedged in between the pulley and belt cover and bending it outward where it was closest. After getting it totally straight I retorqued the 4mm Allen bolt to ensure the key doesn't come out and get lost again.

As expected. Pretty difficult to hacksaw, would recommend an angle grinder to cut it if you have one
