32 mm Rods | McMaster-Carr

A chrome plating on these rods increases their corrosion resistance. They're also hardened, which makes them more resistant to impacts and abrasion. Also known as chrome-moly steel, this versatile 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.

Note: Rods may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Metric Lead Screws and Nuts

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. To ensure compatibility, please select components that have the same thread direction, size, and number of thread starts. Class 7e and 7H components are compatible.

Flange Nuts—Right-Hand Thread

Flange nuts move objects along the length of a lead screw. They have a wide machinable flange for custom mounting.

932 Bearing Bronze—932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Splined Rotary Shafts

Often used in hydraulic and other high-torque applications, these shafts have evenly spaced teeth to transmit heavy rotational loads. They handle more torque and last longer than keyed shafts since they have multiple contact points. Pair them with splined sleeve bushings (sold separately). Compatible bushings and components slide right along the splines, making these shafts a good choice for frequent disassembly and adjustments.

Fully Parallel Splined

The large, straight-sided teeth resemble machine keys and transmit more torque than involute-spline teeth. These shafts are fully splined, so you can mount components anywhere along their length.

Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.

Sleeve Bushings—Transmit rotary motion or position loads along a shaft. These bushings also work as couplers—they can join two splined shafts when welded into place.

Multipurpose 304 Stainless Steel Rods

Made from the most common stainless steel, these 304 stainless steel rods are used to create corrosion-resistant parts for a wide range of applications. Machine them into anything from shafts on chemical mixers to flanges on beverage lines. They maintain their corrosion resistance in temperatures up to 1500° F.
