Selecting Compatible Lead Screws and Nuts

Ultra-Precision 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 Ultra-Precision Lead Screws and Nuts

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

Precision Acme Lead Screws and Nuts

Fast-Travel Precision Acme Lead Screws and Nuts

Acme Lead Screws and Nuts
