Superior holding power over set-screw type collars
ACME Threaded Collars are used on standard ACME threaded shafts, either left or right hand thread). They are perfect for applications such as stroke limiting, stops, and height and spring tensioning. The 2-Piece Clamp-Type design allows the collars to be completely disassembled and placed anywhere on a shaft. They are precision machined, non-marring, easy to adjust, with high clamping power.
