S-95072A881 1/4"-16 x 5/8" Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior wear resistance and durability thanks to 673 Bronze construction with Brinell 70 hardness, ensuring long service life in demanding applications.
• Precise and repeatable linear motion with a 0.063" travel distance per turn, providing accurate positioning control.
• Reliable thread engagement and smooth operation achieved by the Class 2C thread fit for the internal Acme thread, minimizing backlash.
• Versatile integration into existing assemblies with a standard 9/16"-18 UNF external thread, allowing for easy mounting and connection.
• Consistent performance in right-hand drive systems due to the right-hand thread direction and a 1:1 speed ratio for straightforward motion transfer.
• Compliance with environmental and safety standards as it is RoHS 3 compliant, making it suitable for regulated industries.
• Robust construction for heavy-duty use with an externally threaded nut design and a solid 5/8" length, ensuring stability under load.

Professional Applications & Engineering Value

This 1/4-16 ACME bronze lead screw nut is engineered to solve critical challenges in linear motion systems, where precision, durability, and minimal maintenance are paramount. The 673 Bronze material offers excellent corrosion resistance and low friction, reducing wear on mating components like the Acme lead screw and extending the system's operational life. Its Class 2C thread fit ensures tight yet smooth engagement, which is vital for applications requiring accurate positioning without slippage, such as in CNC machinery, precision actuators, and automated manufacturing equipment. The inclusion of a 9/16"-18 UNF external thread facilitates easy integration into various assemblies, while the right-hand thread direction and standardized inch system measurements make it a reliable choice for North American and international engineering projects seeking consistent performance.

Specification Summary & Compliance

This component adheres to Class 2C thread fit standards for the internal 1/4-16 Acme thread, ensuring precise dimensional tolerances. The external thread follows the 9/16"-18 UNF specification. It is manufactured in compliance with RoHS 3 (2015/863/EU), including exemption 6(c) for lead in copper alloys, confirming its suitability for environmentally conscious applications without compromising performance.
