S-95072A213 3/4"-6 x 1 1/4" Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior wear resistance and longevity thanks to 673 Bronze construction with Brinell 70 hardness, ideal for high-friction applications.
• Precise and predictable linear motion with a 0.167" travel distance per turn for accurate positioning in mechanical drives.
• Reliable performance in specialized assemblies due to the left-hand Acme thread, preventing unintended loosening in rotating systems.
• Guaranteed interchangeability and easy assembly with a Class 2C thread fit that accommodates slight variations without sacrificing function.
• Robust connection integrity from a 1/2" external thread length on the nut body, providing ample engagement with mating components.
• Compliance with environmental and safety standards as it is RoHS 3 compliant, ensuring suitability for regulated markets.
• Durable, heavy-duty design with a 1.125" diameter and 1 1/4" length for stability under load in industrial settings.

Professional Applications & Engineering Value

This 3/4"-6 Acme left-hand thread bronze nut is engineered to solve critical challenges in motion control and power transmission systems. The 673 Bronze material offers excellent corrosion resistance and low friction, which is vital for reducing wear in lead screw assemblies and extending service life. The left-hand Acme thread is specifically valuable in applications where reverse-thread mechanisms are needed to prevent unscrewing under clockwise rotation, such as in clamping devices or certain types of machinery. Combined with a Class 2C thread fit, it ensures reliable performance with minimal backlash, making it a trusted component for precision industrial equipment, automated systems, and heavy-duty mechanical drives where accuracy and durability are non-negotiable.

Specification Summary & Compliance

This externally threaded nut adheres to Acme thread standards with a size of 3/4"-6 and a Class 2C thread fit for consistent dimensional accuracy. It features a left-hand thread direction, a travel distance of 0.167" per turn, and external UN threads (1"-18). The component is manufactured from 673 Bronze and meets RoHS 3 (2015/863/EU) compliance under exemption 6(c) for lead in copper alloys, ensuring it aligns with environmental regulations without compromising performance.
