Two-Piece Clamping Acme Lead Screw Collars
Mount these two-piece collars anywhere on an Acme lead screw without removing components. Use them to separate and position components or as an end stop to limit travel. Made of black-oxide steel, they have mild corrosion resistance. Tighten the clamping screw to secure.
To ensure compatibility, please select a collar that has the same thread type, direction, and size as your lead screw.
