Tight-Tolerance Ultra-Machinable 360 Brass Rods

Machine precision parts at whirring speeds without wearing down your tools. These rods come ground to paper-thin tolerances for parts that require pinpoint precision.

Known as free-machining and free-cutting brass, 360 is the easiest alloy to drill, mill, and turn because it has the most lead. You’ll often see it made into gears, pinions, and lock components.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

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 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.

360 Brass

360 brass key stock is corrosion resistant and nonmagnetic. 360 brass is softer than other metals, so it's often used for shear keys.

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.
