28 mm Rods | McMaster-Carr

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance.

Long Rods

Cold Worked—Cold-worked products have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.

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.

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.
