S-95155A319 5/8"-8 ASTM B16 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior wear resistance and durability with 360 brass construction and Rockwell B75 hardness, ensuring long service life in demanding industrial environments.
• Precise and reliable motion control thanks to the 0.125" travel per turn and single thread start, offering consistent linear movement for lead screw assemblies.
• Easy installation and secure fit with Class 2G thread fit, providing optimal clearance for smooth operation and reduced risk of binding in left-hand thread applications.
• Enhanced compatibility and interchangeability with standard 5/8"-8 ACME threading, allowing seamless integration into existing lead screw systems.
• Convenient manual adjustment and maintenance due to the hex nut design, facilitating straightforward assembly and disassembly without specialized tools.
• Corrosion resistance and material integrity from 360 brass, ideal for applications where exposure to moisture or harsh conditions is a concern.
• Compliance with industry standards per ASTM B16, ensuring consistent quality and performance for engineering and manufacturing uses.

Professional Applications & Engineering Value

This 5/8-8 ACME left-hand thread brass hex nut is engineered to address common challenges in lead screw assemblies, such as backlash and wear in repetitive motion systems. Made from 360 brass with a Rockwell B75 hardness, it resists deformation and corrosion, making it suitable for industrial settings like packaging machinery, CNC equipment, and automated positioning systems. The left-hand threading and Class 2G thread fit provide precise, non-standard motion control where reverse direction is required, while the 0.125" travel per turn ensures accurate linear displacement. Its hex nut type allows for easy manual adjustments, reducing downtime and enhancing operational efficiency in B2B applications where reliability and compliance with ASTM B16 specifications are critical.

Specification Summary & Compliance

This nut features a 5/8"-8 ACME thread size with Class 2G thread fit for precise dimensional accuracy and smooth engagement. It adheres to ASTM B16 standards for material and manufacturing consistency, ensuring reliable performance in industrial components. The product is designed with a left-hand thread direction and standard inch measurements, supporting compatibility in various mechanical systems. While not rated for thrust load, it meets general industry requirements for ACME lead screws and nuts, with no specific RoHS or REACH declarations provided, but it aligns with typical material safety guidelines for brass components.
