Clamping Acme Lead Screw Collars

Thread these one-piece collars onto an Acme lead screw to separate and position components, or use them as an end stop to limit travel. Tighten the clamping screw to secure.

To ensure compatibility, please select a collar that has the same thread type, direction, size, and number of thread starts as your lead screw.

Black-Oxide 1215 Carbon Steel and Black-Oxide 12L14 Carbon Steel—Black-oxide carbon steel collars have mild corrosion resistance.

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

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. Tighten the clamping screw to secure.

To ensure compatibility, please select a collar that has the same thread type, direction, size, and number of thread starts as your lead screw.

Black-Oxide 1215 Carbon Steel and Black-Oxide 12L14 Carbon Steel—Black-oxide carbon steel collars have mild corrosion resistance.

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