Tight-Tolerance Ultra-Machinable 360 Brass Rods
- Yield Strength: 25,000 psi
- Hardness: Rockwell B60 (Soft)
- Temper: H02 (1/2 Hard)
- Heat Treatable: No
- Specifications Met: ASTM B16
The diameter of these rods is held to a ±0.0002" tolerance. With the highest lead content of all the brass alloys, 360 offers the best machinability. Often called free-machining and free-cutting brass, it stands up to high-speed drilling, milling, and tapping operations with minimal wear on your tools. It’s commonly used for gears, pinions, and lock components.

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.
Brass key stock is corrosion resistant and nonmagnetic. Brass is softer than other metals, so it's often used for shear keys.
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.
Key stock that meets DIN 6880 conforms to DIN standards for undersized keys.
