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. The threads have a tight thread fit for accurate, repeatable starts and stops. Pair with a motor in automated motion and positioning applications. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.

Precision Acme Lead Screws and Nuts

Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they 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. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.

Thread onto an externally threaded acme nut to create a custom flange nut.

1117 Carbon Steel—Carbon steel flanges have good machinability. However, they will rust when exposed to moisture.

Black-Oxide 1117 Carbon Steel—Black-oxide carbon steel flanges have mild corrosion resistance in dry environments and a dark surface color.

1215 Carbon Steel—Carbon steel flanges have good machinability. However, they will rust when exposed to moisture.

303 Stainless Steel—303 stainless steel flanges have good corrosion resistance.
