Starrett 575BP Screw Thread Micrometer 0-1 Range

Starrett No. 575BP Screw Thread Micrometer provides a 0-1 in measuring range with 0.001 in graduations for precise pitch-diameter measurements on small fasteners and threaded components, making it a go-to tool for machinists who demand consistent, repeatable readings. Its design features a pointed spindle and a double V-anvil that are specifically shaped to contact the thread profile, delivering accurate readings for common screw-thread pitches within the 10-13 TPI range and reducing the risk of fringe contact or misreadings. The instrument is finished in Starrett satin chrome, offering low glare and corrosion resistance while preserving dimensional stability and long-term durability in workshop environments. In practice, it supports quality-control and inspection tasks that verify thread dimensions and pitch diameter, and it is widely used in manufacturing and metrology workflows where precise screw-thread measurements are essential.
