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 carbon steel collars have mild corrosion resistance. 303 stainless steel collars have good corrosion resistance.
