S-95155A351 1"-6 ASTM B16 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 360 Brass construction, ideal for harsh industrial environments and extended service life
• Precise linear motion control with a 0.167" travel distance per turn, ensuring accurate and repeatable positioning
• Excellent thread engagement and wear resistance from the Class 2G thread fit and Rockwell B75 hardness, reducing maintenance needs
• Reliable left-hand thread operation for specialized applications requiring reverse motion or safety mechanisms
• Easy installation and maintenance with a standard hex nut design (1 5/8" width) for simple wrench access
• Guaranteed material quality and consistency through compliance with ASTM B16 standards for brass bars
• Optimized for Acme lead screw systems with a 1"-6 thread size, providing smooth power transmission and high efficiency

Professional Applications & Engineering Value

This 1"-6 left hand Acme hex nut is engineered to address critical challenges in motion control systems where reliability and precision are paramount. Manufactured from 360 Brass, it offers inherent corrosion resistance, making it suitable for applications in moist or chemically aggressive environments without compromising performance. The Acme thread form and Class 2G thread fit ensure minimal backlash and consistent torque transmission, which is vital for maintaining accuracy in CNC machinery, valve actuators, and lifting equipment. Its left-hand thread direction provides a secure solution for assemblies requiring counter-rotational stability, preventing unintended loosening in high-vibration settings. With a Rockwell B75 hardness, the nut resists deformation under load, extending the lifespan of both the nut and mating screw in demanding industrial cycles.
