About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Base-Mounted Shaft Supports

Slide the shaft in to install, then tighten to secure. For use with light to medium loads where shaft alignment is not critical, these shaft supports brace the end of a linear shaft along the ground or other flat surface.

Precision Acme Lead Screws and Nuts

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.

Fast-Travel Precision Acme Lead Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Acme 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.

Cast Iron

Oversized Easy-to-Machine
Gray Cast Iron Rods and Discs

An oversized diameter allows for finishing to your exact requirements.

Oversized Tight-Tolerance
Easy-to-Machine Gray Cast Iron Rods

Precision ground to a tight diameter tolerance, these rods are ready for turning in your lathe.

Easy-to-Machine Gray Cast Iron Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

Impact-Resistant Ductile Cast Iron Rods and Discs

Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking.

Easy-to-Machine Impact-Resistant
Ductile Cast Iron Rods

With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons.

Quick-Clamping Coil-Threaded Rods, Screws, and Nuts

Quick-Clamping Coil-Threaded
Rods, Screws, and Nuts
