These shafts have keyways only on the ends, leaving a plain shaft in the center. Use the keyways with machine keys to transmit torque to gears, sprockets, and other keyed components. Use the middle of the shaft with bearings and other round-bore components.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

The matte plating on these rods increases corrosion resistance and wear resistance.

The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. It's used to fabricate a wide variety of machine parts.

1117 carbon steel responds to surface-hardening heat treatment better than other easy-to-machine carbon steels. Use it to fabricate shaft couplings, studs, pins, and universal joints.

These rods are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress.

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

When compared to standard 304 stainless steel, this material can be machined faster with less wear on cutting tools. It's also called Prodec and Project 70+.

This material has tighter tolerances than standard 303 stainless steel.

This material is hardened for improved strength and wear resistance.

This material machines faster with less wear on cutting tools than standard 316 stainless steel. It's also called Prodec and Project 70+.

One of the hardest types of stainless steel after heat treating, 440C offers excellent wear and abrasion resistance. It's often used for bearings, valves, and knife blades.

Originally developed for aircraft frames, uses for 7075 aluminum now include keys, gears, and other high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

2011 has the best machinability of all the aluminum alloys. It is the most selected aluminum for screws, tube fittings, hose parts, and other items that require extensive machining.

Diameter is oversized to allow for finishing.

Known for its ability to resist stress cracking and fatigue, 544 bronze also offers good formability and excellent machinability. It's commonly called phosphor bronze.

Offering high electrical conductivity and formability, 110 copper is 99.9% pure. Also known as ETP copper, it's often used in electrical applications, such as for bus bars and wire connectors, as well as for flashing, gaskets, and rivets.

Rated RWMA Class 4, 172 beryllium copper is the strongest beryllium copper alloy that is also electrically conductive and extremely wear resistant. It’s often used in inserts, die facings, and molds for plastic that need to withstand stress over repeated use.
