The carbon steel key stock has an unpolished (mill) surface, meets American Society for Testing and Materials International ASTM A108 specifications, and has a standard tolerance. The carbon steel grade provides a good balance of toughness, strength, and machinability. It is magnetic.
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 received this promptly. It's key stock. It does what all key stock does. I got this 12" stick for about the same price as 3-2inch pieces would have cost me. With this I could cut the exact length I wanted.

This is a simple keystock for a good price. I used more than half of it for my purposes. I'll see if it holds the torque i put on it

The dimensions were exactly perfect, the bar is high quality and 3lbs 6oz. Packaging was okay, bar was in a plastic bag than placed inside a paper shipping bag.

Key stock came quickly and as described. The tolerance was perfect no work required to perfectly fit a 1/4” key way.

I used this to install torque converters on a Predator 212 engine and also A titan 6.hp engine. I had to cut it to length but the width was a perfect fit for the keyways and no issues at all.

Very happy with the steel, but beware Amazon packed this order very poorly, as is becoming common. When I picked up one end of the box from my doorstep, the steel bar literally fell out of a gaping hole on the other end.

Used this and some different sized carbide cutting tips and made some really nice lathe wood cutting tools for about $15 each. Saved a huge amount and works great

What can you say? It's 3/16" square stock. Seems within tolerances, and works well for my purposes. I use this mainly for aligning vintage Sunbeam Mixmaster brush holders. With the armature and brushes (3/16" square carbon) removed, shove this in one brush holder and out the other, set it straight to the mixer body, tighten the set screws, and voila! Both holders are lined up properly with the commutator and each other. Nice.
