S-95270A514 1/2"-10 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 and predictable linear motion with a 0.1" travel distance per turn, ensuring accurate positioning in automated systems.
• Enhanced durability and wear resistance provided by a Rockwell B55 hardness, reducing maintenance needs and downtime.
• Reliable, free-spinning assembly due to the Class 2G thread fit, which facilitates easier hand assembly and reduces galling.
• Optimized for non-reversing applications with left-hand Acme threading, providing a secure connection where standard right-hand threads might loosen.
• Stable mounting and torque resistance from the square nut design, preventing rotation during operation and simplifying installation.
• Guaranteed material quality and consistency through compliance with ASTM B16 standards for brass bars.

Professional Applications & Engineering Value

This 1/2"-10 Left Hand Acme Thread Brass Square Nut is engineered to solve critical challenges in motion control and power transmission systems. The use of 360 Brass offers excellent machinability and inherent corrosion resistance, making it a superior choice for applications exposed to moisture, chemicals, or marine environments where steel components would fail. The Acme thread form is specifically designed to handle high-load, low-speed applications with minimal backlash, which is crucial in precision lead screw assemblies for CNC machines, valve actuators, and lifting equipment. The left-hand thread direction is a key feature for creating locking mechanisms or for use in systems where the rotation would otherwise cause a standard right-hand nut to disengage. Combined with the Class 2G thread fit, this nut ensures reliable performance, reduces the risk of seizing, and extends the operational life of the entire assembly, delivering long-term engineering value and reliability.

Specification Summary & Compliance

This component features a 1/2"-10 left-hand Acme thread with a Class 2G thread fit, providing a standard tolerance for general purpose, free-running assemblies. The nut is manufactured from 360 Brass and conforms to the material specifications of ASTM B16. The dimensional profile includes a height of 1/2" and a width of 7/8" in a square nut configuration. This product is designed and produced in accordance with standard industrial manufacturing practices for mechanical components.
