Key Features & Benefits at a Glance

  • Superior wear resistance with Rockwell B55 hardness for extended service life in high-use mechanical systems.
  • Precise linear motion control due to the 0.167" travel per turn, ensuring accurate positioning in lead screw assemblies.
  • Excellent corrosion resistance from 360 Brass material, ideal for environments where moisture or chemicals are present.
  • Reliable thread engagement with Class 2G fit, providing consistent performance and reduced risk of backlash.
  • Broad compatibility with standard 7/8"-6 ACME threaded lead screws, simplifying integration into existing setups.
  • Smooth operational efficiency from the single-start, right-hand thread design, minimizing friction and wear.
  • Assured quality and consistency through compliance with ASTM B16 specifications, meeting industrial standards.

Professional Applications & Engineering Value

This 7/8"-6 ACME thread brass nut is engineered to address common challenges in precision mechanical systems, such as wear, misalignment, and corrosion. Made from 360 Brass, it offers inherent lubricity and resistance to galvanic corrosion, making it suitable for applications in machinery, automation, and marine environments. The Class 2G thread fit ensures tight yet smooth engagement with lead screws, reducing vibration and enhancing positional accuracy. With a single-start, right-hand thread and 0.167" travel per turn, it provides controlled linear motion, ideal for CNC equipment, lifting mechanisms, and valve actuators where reliability and durability are critical.

Specification Summary & Compliance

This nut features a 7/8"-6 ACME thread with Class 2G fit per inch standards, ensuring dimensional accuracy and interchangeability. It complies with ASTM B16 for material and manufacturing consistency, and the 360 Brass construction supports adherence to RoHS and REACH directives for environmental safety. The single-start thread and right-hand direction provide standardized operation, while the Rockwell B55 hardness confirms mechanical integrity for industrial use.
